His position was ridiculous and he didn't have a leg to stand on, and the interview showed it clearly.
But the worrying, and astonishing, thing is that this is what a great many under-informed and misled people think. Not necessarily stupid people either. And they can be very well-meaning. They think this because despite the detail of wherever the latest twitter arguments and definitions are at, the "born in the wrong body"/"poor sad persecuted trans person who has a male body but is [somehow] actually a woman" has been hammered into our collective consciousness for a long time now - not just the past few years. i thought this myself in a vague kind of way until the demands became more overreaching and it started being a big thing for kids, and I started thinking it through logically and looking for actual evidence.
This is why so many teachers, parents and general allies think they are just being nice and anyone who questions it is a nasty meanie.
Speaking the truth is shocking to these people because so many have sleepwalked into accepting total meaningless nonsense as fact.
