I watched the video even though I despise Letterhole, but I did not see any mocking of her/him/it. This group should not get their jockey shorts/panties in a bunch over this...
Homosexuals and transgendered persons are mentally ill. They are constantly looking for any and all possible scapegoats to blame for their mental pain. Of course you already know that.
I think Letterman is bullet proof these days. Tiger did not follow suit.
I think the proper pronoun would be:
She/he/it
...But if one were to say THAT a little too fast, it would present it’s own set of problems.
