To me, is not talking about what trans is, but objecting to the current trans ideology and why it is toxic, and not like the gay rights movement. That is enough for the moment, I think. And frankly where the push has to come from, from gay men and lesbians showing others that trans isn't just like gay was, since pretending it was is part of the reason it has got so far so fast.
He has kept it simple, said rights for trans people are important, but not like this. The current approach is not good. I particularly liked the softly-spoken statements about transing the gay away.
