[question] Do you think project 2025 could realistically be implemented or be applied?

I suppose it depends on which part of the "plan" you're referring to. The parts where they want to strip down the bureaucratic state (federal agencies etc) is probably somewhat achievable under executive authority, but that will still take a while to accomplish because there are procedures in place that prevent just wholesale doing away with a lot of stuff, not to mention the court cases that will likely arise out of some of that.

To relieve a little bit of panic, something like banning pornography as a general statement (even the GBT portion) is going to be a major uphill battle, even with the conservative majority SCOTUS. The conservatives on the court are largely originalists, and despite being conservative they take a pretty hard-line free speech view of most things - the "test" that they use revolves around determining if the speech is calling for action that will cause imminent (physical) harm. Pornography does not meet that threshold.

Edit: To address defunding public schools, those are run by states. The Dept of Education gives some money to them, but most school funding in most places is acquired via property taxes or other local taxes for the area. The Federal government, project 2025 or no, can't do much about that.

Whose gonna stop them? Last time they were in they banned abortion, and no one stopped them. Sure there are states that habe made it legal, but by and large, it worked for them.

I cant see mainstream porn being banned, given its a huge business, but GBT porn probably would get banned without any major business opposition. (Im considering lesbian porn as mainstream, as its mostly targeted to men)
