Hate is a fairly strong word. I think a more accurate description of the Republican stance on transgenderism at the moment is "don't want to support it at all". And even then, that is almost entirely in reference to children. But it sounds like OP can perfectly well support themselves, so not sure that would be an issue as a member of that group.
again, the GOP in the months leading up to the election spent more on anti-trans rhetoric than all other issues combined, including immigration and the economy. if you saw any of these ads and the literal hate being spewed, you maybe would understand better.
