Schumer is disgusting.
I don’t know why she is famous. She is not at all attractive, and per personality is rough, crass and uncouth, and otherwise unremarkable.
Men can be funny. Women can be funny.
Men can "go blue" and be crass and uncouth and still be funny. It's a matter of taste and opinion, but it can happen.
However - women trying to act like uncouth, crass men - not funny. And certainly no more funny than a man acting like an uncouth, crass woman.
