This seems a bit confused to me, but I think it's the way it's written - do you mean that a gender identity that seems to be opposite to the person's real sex only makes sense if it isn't connected to the person's sex?
I'm not really sure what you mean here, but I think my meaning might have been clearer if I had said simply 'identity' instead of 'gender identity' (because try as I might, I cannot comprehend what a 'gender identity' is).
So what I was trying to say is that this idea of an identity which is that of the opposite sex only makes sense if you assume that personalities or self image are somehow connected to one's sex. Sex is a biological fact which can't be changed, so your identity or personality is constructed around this immutable fact, but should not be in any way restricted by it. Is that any clearer?
I also think this is part of the reason teenagers, who are in a period where cultural identity is being formed in a very intense way, are so vulnerable to being told untruths about gender identity.
I agree with this, and it's why people have sometimes commented that 'gender identity' is 'the new goth'. With teenagers there's a lot of trying to fit in going on as well, so for those who don't, an opposite sex 'gender identity' or identifying as 'non binary' gives them a way of belonging, or an explanation of their failure to fit in.
But I was responding to a very specific point, criticising Debbie for saying that as a child the sense of gender identity he experienced seemed to be attached to "girl".
This is where I get lost. It's that idea of a 'gender identity' again. Why is 'gender' attached to identity? There are people of both sexes and there are personalities. Why should any particular personality belong to a particular sex. I really don't get it at all.
