Project 2025 was a massive nothingburger created by some people that had some connection to trump. They are basically a think tank that goes " hey, wouldn't this be cool" to the president every 4 years. Dems flipped the fuck out despite a good portion of the proposal being shit they already do anyways. Trump ended up disavowing it, multiple times. This is combined with half truths and fanfiction about what it actually was. Maybe Trump was planning to use some proposals, maybe not. And largely, that doesn't matter.
The heart of it is that they try to tell you that trump is secretly has some shadowy plan that he's hiding, as told to you by a group that does nothing but hide and gaslight at every turn. It's very telling that when my teacher talked about trump's policy, she didn't even know that he had an official website by him with his own policies on it. All she was told was Project 2025. And she still took issue with the official policy list, so I don't get how Trump would have some secret hidden agenda when people already complain about his official one.
