A mostly Hispanic Miami police captain has been suspended for identifying as black when he took an exam for promotion.  His playing the system beautifully exposes the ridiculous way in which leftists manipulate both sex and race.

Sex is biologically determined.  Barring a minutely small subset of people born with mixed-up chromosomes, human females have XX chromosomes, and human males have XY chromosomes.  These chromosomal differences result in different body types, different reproductive functions, and different areas of strength in the brain.  They make women and men separate but equal parts of a single species.

Leftists, though, reject entirely the idea that sex is biologically fixed.  They are determined to make people believe that a person's sex is whatever that person says it is at a given time on a given day. This is a grotesque and pernicious idea that is terribly damaging to young people who lose touch with their own identity and are often pushed into destroying their body with cancer- and sterility-causing drugs and mutilating surgery.

Not only do leftists destroy young people's brains and bodies, but they are destroying anyone who opposes the idea of infinitely mutating sexes.  A few days ago, Jon Caldara, a libertarian columnist for the Denver Post, said he was fired for insisting that there are only two sexes:

My column is not a soft voiced, sticky sweet NPR-styled piece which employs the language now mandated by the victim-centric, identity politics driven media.

Plain talk that doesn't conform to the newspeak law of "use only the words mandated by the perpetually offended." So, it is labeled as "mean spirited" and banned.

What seemed to be the last straw for my column was my insistence that there are only two sexes and my frustration that to be inclusive of the transgendered (even that word isn't allowed) we must lose our right to free speech.

I don't care who uses whose bathroom, what you wear, or how you identify. People from this community have rights which we must protect.

But to force us to use inaccurate pronouns, to force us to teach our kids that there are more than two sexes, to call what is plainly a man in a dress, well, not a man in a dress violates our right of speech.

YOU are free to wear a dress, and quite sincerely, more power to you! That's power over your own self. You are sovereign.

And so am I. Which means YOU cannot choose my words. Our words are now chosen by the press, and our kids' words are being mandated at school.

Although sex is biologically fixed, race is not.  While there are racial genes many of us indubitably do not have (e.g., genetic tests show that Elizabeth Warren has no Native American blood), the reality is that race is more malleable than sex.  Obama, a man half-black and half-white, chose to identify as black.  The media identified George Zimmerman, a man half-Hispanic and half-white, as white because it suited them to do so.

Many of us have been surprised to learn that our genetic history is different from our cultural assumptions.  Indeed, if one wants to really press the point, every last one of us can claim African heritage.  That is, after all, our common human point of origin.

Police captain Javier Ortiz may have figured out that, just as sex is what you want it to be, race is, too — especially if, like Ortiz, you actually have a genetic racial lineage:

"I learned that there are people in my family that are mixed, that are black," Ortiz argued. "And if you know anything about the one-drop rule, which started in the 20th century, which is what identifies and defines what a black man is, or a Negro."

Ortiz got in trouble, not for being black, but for switching races, depending on the benefit he could get from claiming to be one race over another:

Miami Police Capt. Javier Ortiz appeared in front of Miami's city commissioners last week to face an allegation that he identified himself as a black man on an exam so that he could get a promotion, NBC News reports.

"The question is why is it that every time he finishes an exam, he goes back to white Hispanic male?" Sgt. Stanley Jean-Poix, president of the majority-black Miami Community Police Benevolent Association, questioned.

Maybe rather than castigating Ortiz for trying to game the system, blacks should be asking why the system treats them as stupid people who can only take easier tests.  That seems to be the really offensive assumption at work here.
