One thing that I can absolutely grant to the trans-activists (again, I'm referring to the activists, not trans people) is that, yeah, as something becomes more culturally accepted, more people come out of the closet, and that's a good thing.
Yeah, as homosexuality became more normal, gay people became more comfortable living their lives openly. That's a good thing.
What we didn't see as we gradually, all too slowly, began to accept homosexuality was a 4,400% increase in people coming out as gay. That's the increase that we've seen in young girls identifying as trans.
