Nothing is more obnoxious than calling someone a liar just because they disagree with you.

Unless of course, it is true.

And it is getting harder and harder to describe the recent black mob violence near Milwaukee without using the word L-word aimed directly at reporters and public officials who ignore, deny and try to wish it away.

The latest case happened Saturday night in the Milwaukee suburb of Wauwatosa. Every year, they have a Tosa Fest, complete with ring tosses, pretzel booths, and this year, a free outdoor movie, Cloudy With a Chance of Meatballs II.

It is supposed to be a family affair. Not this year. A large group of black people were milling around, then attacking people, then throwing things.

It got so bad they cancelled the movie.

The Mayor said “several” people had a brawl. An “isolated” case of violence. Jim Stingl took to his column at the Milwaukee Journal Sentinel to let everyone know this was not a case of black mob violence — the kind they had at the Wisconsin State Fair a few years ago.

“As you can guess, the concern over TosaFest is partly about skin color,” said Stingl. Both black kids and white kids were causing the disturbance. “They were all hanging out together.”

Isn’t that a nice lie.

Talk show host Jeff Wagner went along with it: Those darn teens were at it again.  Violence had nothing to do with race, get it?

More and more people in Milwaukee do not.  They say Tosa Fest was just another example of the black mob violence that “ruined” the State Fair. This violence was captured on 911 calls that allowed people to hear accounts of hundreds of black people storming in and out of the fairgrounds attacking white people and destroying property.

Others recalled the black mob violence at the Mayfair Mall that caused shoppers and store employees to cower in fear in dark closets as they called 911 and begged police to hurry.

Those 911 calls are available here.

Some remembered the black mob violence that forced Greek Fest to move to more secure quarters. And cancel River Splash all together.

Though you won’t find a reporter in town to say so.

Others remember the July 3 case of black mob violence made famous in that best selling book White Girl Bleed a Lot, authored by your intrepid correspondent. Videos show 50 to 100 black people looting a grocery store, then taking their stolen goods to a nearby park. There they beat a few white kids. At one point, a black woman was standing over a white girl, and motioned to her friends to look down at the prostrate figure: “White girl bleed a lot,” she said.

Everyone thought that was very funny. Except the victims.

This is a long list: The Juneteenth party is an occasion of regular black mob violence in Milwaukee. In 2012, hundreds of black people rampaged, assaulted, fought with police and destroyed property. They even attacked a horse.

A local news helicopter captured some of the carnage: Hundreds of black people storming up a street, surrounding a car, pulling the occupants out, beating them. Then doing it again to another car. More victims.

As the aerial footage played as B-Roll behind a reporter for WTMJ, he  said — with a straight face — it was too bad just a “few people” could tarnish the reputation of such a nice event — for the second year in a row.

Over the summer, two black people were shot and killed during robberies and assaults during episodes of black mob violence in an upscale shopping district. Police estimate this group was responsible for dozens of cases of violence and mayhem during a two month period.

Of course, that does not count the two black people who were shot and killed after their group attacked, held down and beat a janitor with a baseball bat. He took out his gun and killed two of them. Their families demanded the janitor be arrested for murder because the people he killed were good boys who were on their ways to college where they were going to study (nuclear physics or something like that).

And lots of others remember how Seandell Jackson and his buddy killed “the white boy” Nathaniel Potter and how, in court, Jackson’s friends taunted and threatened the family of the dead man: “We hate you,” they screamed.

Roller skating rinks, soccer fields, funerals, nightclubs, schools, buses, court rooms, you name it, the folks in Milwaukee can recite details of black mob violence there much the way they used to talk about Hank Aaron and the Milwaukee Braves.

And of course, the Knockout Game is as popular here as anywhere.

Racial violence is an accepted fact life in Milwaukee for just about everyone except the Liars for Hire who call themselves reporters.

Ten years ago, they could — and did — get away with it.  But today, there are too many victims, too many videos, too many witnesses, too many Tweets, too many people demanding truth, too many people telling the real stories in the comments section and on talk radio.

On the Jeff Wagner show in Milwaukee, the host was doing intellectual cartwheels to avoid using the term black mob violence. His first caller during his segment on the Tosa Fest put that to rest right away. She was there: She saw a “segregated” crowd of 400 black people.

“My daughter was there and yes, it was black youth,” said another witness posting at the Journal Sentinel web site. “ She said they swarmed in and started screaming and throwing things.”

Other readers castigated her as a bad person for noticing. Most of the deniers did not really deny it that black people were responsible: They just denied it was worth noticing. No matter how wildly out of proportion black on white crime and black mob violence might be in Milwaukee and the rest of the country.

“Just how dumb does the JS think people are?” asked another. “Think Greekfest. Think Chuck E. Cheese at 124th & North. A group of youth from 10 to 20? Puh-leaze!”

A local who called himself Jack Masters chimed in on Twitter: “Grew up in Tosa. Met my wife in Tosa. Used 2 love #TosaFest. Now Da Thugs have ruined that too. Congrats. Gonna blame the whities 4 this 2??”

Black people at the Tosa Fest agreed: “TosaFest Was fun until they started acting a fool,” said Daeja_Waejaaa on Twitter.  “Another thing the white ppl can say about us Blacks.”

The “ganga gang banger” over at Instagram posted pictures of his friends and him flashing middle fingers and gang signs during the Tosa Fest.

A black teenager blogger put it all in perspective on YouTube. He had no trouble figuring out who was causing the violence and mayhem at so many public events in the Milwaukee area prior to Tosa.

His name is Mike Hagler and he does not want to hear any more excuses for riots at the Wisconsin State Fair. Or gunfire at the Juneteenth celebration. Or any other black mob violence.

“Every time there is an event going on, people want to pull out guns and go crazy,” said Hagler, “Everything is getting cancelled: State fairs. Summerfest. All people want to do is fight. Y’all acting like animals. And it is crazy to say it is our own people acting that way.”

He continued, “It’s crazy when you go to an event and there be a majority white people there. As soon as black people come around that get to moving out of the way. They already know what is going to happen.

“It’s like when you want to go to Juneteenth. I ain’t going to go to Juneteenth because people already know what is going to happen. People are going to be shooting and fighting.”

Back at the Milwaukee Journal Sentinel, one of Stingl’s more subtle readers summed it up: “I thought kids did this because there was nothing for them to do?  Seems like Tosa Fest was something to do.”
