Project 2025 and the conservatives want to ban everything that makes life even marginally enjoyable. No porn, no alcohol or Marijuana, they want to make all my gay and transgender friends illegal and treat women like A Handmaid's Tale.
I am simply too disillusioned or maybe not strong enough to live through that, seeing all of our rights taken away until all the Bible Belt Boomers can finally feel safe at the end of their life. Fuck off, I hate these virtue-signaling assholes who just want control and theocracy.
I hate Trump but IMHO (I wouldn't be on this site if I were only saying this to be pro-life) none of these are likely to happen. Also disclaimer that I'm British, but I'm a little bit autistically obsessed with US political & government stuff.
Weed is already criminalised federally; if the federal government tried to prosecute for it even in states where it's legal, they'd piss off both the stoners
and the states' rights crowd. Criminalising alcohol would be an even bigger vote loser.
It's plausible that gay marriage becomes something where only some states can recognise it;
Obergefell is the only thing standing in the way of that, and the current Supreme Court's composition might be keen to overturn that. But it's unclear to me whether Trump would even choose to go after gay people to do more than that. Recall that Trump was the first US president to voice support for gay marriage before inauguration day. He surrounds himself with lots of Christian types because he's in right-wing American politics and they're
everywhere, but he'd only actually go after gays if it benefitted him in some way. And I really don't think it would - it'd galvanise the very fringe of his base who were going to support him anyway & repulse everyone else.
There are definite links between Trump and the Heritage Foundation, but most of the Project 2025 stuff I don't think is likely to actually happen - Trump cares only for himself and his popularity, and he wouldn't want to split his own base with insane policies. My concern here is that the politicisation of the Executive Branch might enable him to weaponise it to help in his scheming like he did post-2020 (stuff like getting an Attorney General who'll support his bullshit claims). But this is different to your fear.
Also, probably most importantly: a lot of this stuff is unconstitutional. Sure, abortion used to be considered a constitutional right, but it was on fairly shaky legal ground regardless.
Roe identified the right under the "penumbra" of multiple separate rights, under a theory that the conjunction of these rights confers a right to an abortion. Even legal scholars are torn on this - while IMO the ruling had positive impacts - the actual legal grounds undergirding it weren't hugely compelling in the first place.
But when it comes to stuff like theocratic government, this is a very clear-cut constitutional violation: the Establishments clause explicitly prevents this. I don't think even the current Supreme Court, with the wacky decisions it's made so far, would uphold an explicit policy decision made on religious grounds. We have to look at a case-by-case basis of which Project 2025 wishes could survive legal challenges.
As to why Trump even hangs out with the Heritage Foundation guys at all: I think they probably just give him lots of shit. Like they help galvanise his Christian base a lot, and probably give him lots of money (& free trips on a private plane!). And some parts of Project 2025, like the aforementioned politicisation of the civil service, are things Trump wanted to do anyway. But at core, Trump cares solely for himself. And going after the gays will not help himself at all, even if he somehow succeeds at getting it through the courts.
tl;dr (sorry I'm stoned and wrote more than I should've): Trump has 0 thoughts about anything other than himself, and doing a lot of the stuff you described would NOT help him at all. Also good chance some of this stuff wouldn't survive in the courts.
