I
half agree. On the one hand, I don't like that it's being framed as a left/right issue because it really isn't. It's an ideology that threatens civilization as a whole IMO, and any reasonable person should be against it regardless of individual political positions. In fact it's really beyond politics, it's a philosophical question - it challenges our basic conception of such fundamental truths as the difference between men and women, and the ethical norms that mean we treat them differently. So the fact that Trump/his administration is so gung-ho about it is potentially troubling as it could cause some leftist/liberal types to dig in their heels and stay longer in gender fantasy land than they otherwise would have done. I would like to see a broader opposition to this bullshit across the political spectrum.
But no I don't think it's too heavy-handed
at all. It's being framed that way, but that's only because we dived so deep into this lunacy in the first place. Pointing out that only two sexes exist, which are immutable, is reasonable and correct. Not allowing men into women's toilets is reasonable and correct. Not allowing men to compete in women's sports is reasonable and correct. None of this is extremist in any way, it's just being responsible. It's a shame that we've got to the stage where we have to put our foot down on these things, but that's where we stand. It's not Nancy Mace who is at fault for forcing troons to use male bathrooms in the Capitol - it's the
troons' fault for trying to get in. I think you're being overly pessimistic about the public's reaction to this as well, because of course a group of them immediately decided, in typically tactless and self-defeating fashion, to invade the women's facilities and prove that they don't belong there:
They're the ones that look bad here, and the majority of Americans can see that. Sure, the insane hardliners will become that little bit more insane and hard-line, but they're not the people who will ultimately win or lose this fight. It's ordinary members of the public who are just fed up of this shit who will decide the future of the trans movement.
Rate me

if you like, but I firmly believe that the tide has already turned on this. I know it's anecdotal, but I know quite a lot of people who were firmly pro-trans a few years ago who have now either softened their position substantially or have completely peaked. In the US, I think we'll have a better idea of what the future holds in 2028 - will the Democrats choose a candidate who panders to troonery, and will he or she win? I think the answer to that question is going to have big implications. If a pro-trans Democrat loses or a moderate Democrat wins then I think that'll be the nail in the coffin of the movement as a political force, at least until the younger generations come of age. If one of the other two scenarios happens then we'll have to wait and see.
In the UK I think it's already done for. The Conservatives and Reform both seem committedly against trans dogma, and even Labour is lukewarm at best, and those are the only parties with any hope of winning an election as far as I can see. It's a vote-loser and in the end that's what matters.
