Why can't fudies show conclusive proof that these people act in such a manner in front of Children

See here & here for examples.

Also from the first:

Kevin Whitt is a former drag queen who lived for over 20 years as a transsexual woman. Now he protests drag events for children and fights to stop the gender modification procedures for children.

Funny thing is that he was never transsexual to begin with. If anything they are conflating being trans with doing drag

Well, he is “trans”. Men who dress as females are transvestites, not transexuals.

No that isn’t how it works. Drag is performance, transvestites have a fetish.

Female impersonation is a performance, drag moves more to fetish in my opinion. But you are correct.
