As others have said transphobia in Britain is very much an elite bigotry here with a lot of institutional capture by TERFs across the political and media spectrum. "Normal people" are usually at worse ambivalent but mostly people have a "mind your own business" kind of attitude.

Relatedly, I met someone recently who was an anti-vaxxer and bit of a conspiracy nut who I think voted for Reform but he was extremely accepting towards me. If you want to visit, don't let our horrendous political-media class put you off. That's something more that us Brit trans' have to deal with.
