Not really sure how to word this but hoping someone slightly more eloquent than me can help me get my thoughts in order. This is something I've seen people bring up time and time again, and it frustrates me that I find it difficult to construct a decent argument against it despite feeling instinctively that it's a load of rubbish.
I often see people compare the treatment of gay people to the treatment of trans people. For example, I've seen people argue that saying trans women aren't women is the same as saying a gay person is just going through a phase. I've also seen people argue that suggesting the best thing for a young 'trans' person might not be to start taking hormone blockers or have surgery is similar to advocating for conversion therapy for gay people.
I don't believe these things are particularly similar but find it difficult to verbalise why. I think at its core it's that the only requirement for being gay is being attracted exclusively to the same sex, and that feeling is completely internal - nobody other than you can say whether you are or are not gay. Being trans, on the other hand, is related to physical reality and claiming to be a woman when you biologically aren't one isn't correct. Can anyone explain simply why the comparison doesn't work?
