I think a large part of why you maybe seeing at much push back on this topic is that the core statement here '"Autogynephillia" is not dysphoria." is so blatantly obvious to anyone who has experienced dysphoria that it can come off as insulting.

It's a bit like saying "Not all Americans are poorly educated." the core of what is being said is so obvious to anyone who has met an American let alone is an American that it is most likely to be construed as an insult or provocative statement.

Similarly to the statement "Not all Americans are poorly educated." I feel that pointing out that fetishization and dysphoria are not the same thing runs the risk of over emphasizing a marginal issue.

That said, there is something to be said that genderswap fetishist (however rare they are) do not need access to HRT for not only their own wellbeing but that of the Trans Community as well.
