TV shows/movies generally do more to demonize/caricature those who crossdress and make them look bad compared to what Real Life examples do. Ones in Real Life tend to have more neutral presentation/motivations, and YouTube may similarly tend to lack the sort of cues more common in popular media.
I personally haven't looked around YouTube too much, but TV/movies tend to perpetuate stereotypes and harmful images of various minorities, so there's a certain justification for your feelings, and you could see you'd probably have those kinds of feelings towards other groups as well (gays, Muslims, etc...).
