That isn’t going to happen, lol.
Trump is pro-LGBT. He won’t let it happen.
Name specifically the LGBT rights that can be rolled back…Trump won’t let Same-Sex Marriage be undone. As far as Trans rights, I don’t think the Supreme Court can do anything.
Even then, it’s him or Hillary that wants to demographically change the country from White, tolerant Liberal to Homophobic, Ultraconservative Hispanic Catholic.
