People saying Trump is "so right" on the issue need to understand that in the US gender-critical outlook is part of the overall conservative agenda. They don't have anyone otherwise progressive questioning any of the trans ideology; they have no TERFs to speak of, TRA it is still widely accepted and seen as a sign of being liberal and "left" (even thought there is no "left" in America as far as I'm concerned).
Trump's views on trans politics is part of the narrative that includes stopping gay marriages and adoptions, criminalising abortions and generally reducing rights of women - for him and his supporters its all the same thing. So I would not be cheering any of the shit coming out of Trump's gob, its not based on research or progressive ideology but on rampant homophobia and insane religious radicalism.
