Oh way to completely twist things.
If a black employee complained that someone was performing in “blackface” at their place of work, would you complain as much as you are in this situation? I’m betting not.
As for what happened, I can only go on how it’s been reported here so, get over yourself! It’s a drag act for god’s sake. Drag queens have the most vicious tongues, catty / bitchy etc, but it’s a persona, an act, it’s to entertain. If you felt that uncomfortable about it you could have taken the night off.
Talk about mountain out of a molehill!
