Picking on drag queens and trans kids is not a random choice in the culture attacks.  They are small populations and few people have regular contact. Gender dysphoria seems unreal because they do not understand it, as if quantum mechanics is unreal owing to their ignorance of the subject. and, course, it would never occur to them to inform themselves. But, in fairness to these ignoramuses, books dealing with these subjects are banned or have been burned to protect them from knowledge.

The vulnerability of drag performers and trans people make for handy targets and serve as a means to conflate them with the larger LGBTQ community and make it easier  to come after the whole lot.  And, of course, this is but a part of the fascist plot to "eradicate" or otherwise repress those Americans they do not like.
