This has been exactly my experience as well, and why I am increasingly comfortable with skepticism of unqualified conservative voices as a default.
I have been having good faith debates over real policy with conservatives for three decades. Since Carter more or less. I know what that debate looks like. But since 2016, I know two types of former conservative - the reformed, who were awakened to the monstrosity that Trump created. And those who openly embraced fascism like a parasite embraces dog shit.
Every person. Every single one so far, who has been equivocal on this topic has turned out to be quietly the latter. The ones belonging to the former group are very open about feeling dumb and misled, even victimized. They express loudly and often the nature of their reform to anyone who will listen.
I’m sorry but if you are an lgbt republican then you are among the stupidest people to have ever lived.
