It's great, but it's just common sense.
Trump has the ego/ confidence to say the emperor has no clothes. To say - you can call me a bigot and threaten me all you like but this is nonsense, everyone knows it's nonsense except those who've lost their minds. He knows this has won him votes not lost them, he's got nothing to fear from stating biological facts.
Gender ideology is literally the most science denying batshit delusional insanity that I think I've ever come across - far far worse than flat earthers, creationists or anti vax. It's an abusive ideology at core that encourages it's followers to be abusive (see all the court cases that lay this bare). The fact it has become embedded in institutions the way it has is really frightening.
Trump just has the guts to say what everyone else with the tiniest grasp on reality wants to - because he's powerful enough and doesn't care what the cowards pushing all this harm think of him.
I hope he does what he says he'll do.
