Are you seriously making this argument?

"We can't allow people to admit they are gay in a speech, because then we would also have to allow genocidal Nazis to speak."

What is the difference between a young man talking about how hard it is to be gay and another young man advocating mass extermination.

Simple - one of these is EVIL.

Equating a compassionate person talking insightfully about their own life with someone advocating for genocide shows a depraved indifference to right and wrong.
