Many of us remember a time in school when a girl's desk suddenly went empty.  But, thanks to the left, those desks no longer are abandoned.

From Wikipedia:

In the common law of negligence, the doctrine of res ipsa loquitur (Latin for "the thing speaks for itself") states that the elements of duty of care and breach can be sometimes inferred from the very nature of an accident or other outcome, even without direct evidence of how any defendant behaved.

I think the keepers of our culture are guilty of negligence as exemplified by the inimitable New York Senator Daniel Patrick Moynihan in the phrase and concept of "defining deviancy down."   It is:

...lowering the bar for what was once considered deviant behavior, giving a pass to things society once scorned.

Well, Jerry Scott & Jim Borgman, creators of the comic strip, Zits, picture the consequences of that negligence perfectly here:

Some may think this progress by the removal of a stigma.  I think it's what happens once the camel's nose intrudes or the thin edge of the wedge is inserted under the foundation.
