I have had another thought:
If it is (rightly) unacceptable for white guys (oppressor class) to black up for a party or Othello and that, why should it be acceptable for men (oppressor class) to pretend to be women on stage? Often in a hyper sexualised, hyper feminine or otherwise goady way?
Surely one is racist and the other sexist?
And if you agree, then surely THAT'S why young or vulnerable people shouldn't be getting involved with the drag - because it's sexist. And a child or perhaps someone with DS can't be expected to understand that aspect.
It's making sexism fun, I get that.
Please don't anyone think I'm some sort of killjoy fuddy duddy. Sarcasm emoji.
