If you doubt the validity of their inclusion in the sheep herd, just remember, when Bradley Edward Manning decided to "identify" as Chelsea Elizabeth Manning, libertarians were among the first to cooperate and start calling him that, and immediately switched pronouns. Their justification was exactly the same as the rationalization you heard from the left, that it was up to Manning to decide what he was, and nobody else had any business refusing to comply, no matter what the pesky facts were. With libertarians like that, we don't need any liberals.
And by now we've all heard about Rachel Dolezal, and we're expected to take that seriously.
Sometimes little kids get deeply into play, and insist that they are soldiers, or aliens, or superheroes, or some other fun thing, and want to be called "Sargent" or "Spock" or whatever, and sometimes adults fondly go along with the game. It's fun. But it's make-believe. And past a certain age, make-believe stops being cute and gets creepy.
It's creepy, folks.
And I know I'm right about this, because I identify as right.
But while there are still limits to it, we can enjoy the humor of exaggeration. Let's enjoy it while we can. At Unz Review [link], Fred Reed writes:
