And yes their absolutely are trans children, very rare pre puberty but we have (now adult) person in the family, as young as 3 was saying it
You do realise, I'm sure, that 3 year olds say all sorts of things, some of which make no sense whatsoever? Also that 3 year olds pretend to be all sorts of things that they are not.
was expressing gender non conformity at preschool age
What on earth has gender non conformity got to do with this? Have we gone back in time 10 years? Nobody even suggests any more that gender stereotypes have anything at all to do with transgenderism.
Gender identity and transgenderism are now all about how a person 'feels inside'. It's nothing to do with stereotypes. And how a person 'feels inside' to a large extent cannot be described, so we have no way of knowing if one person who claims this feeling has anything in common with others who do. Of course 'gender identity' also has no real definition and nobody can explain why the way a person 'feels inside' should have anything to do with how other people treat them or talk about them.
It's bizarre that this absurd belief system has been foisted on children, particularly children who have complex care needs already.
