Bear with me here, I know you know all this but am putting some thoughts down after a discussion with my DH.
'I am a woman because I feel like a woman'
'I identify as a woman therefore I am one'
These statements don't make sense. In order to know what you identify as, you have to be able to define that thing- its characteristics.
'I identify as a woman therefore I am one'
'What makes you know it is a woman you identify as?'
'I feel it'
'What do you feel? What makes that a woman'?
There is no way to proceed with this other than to be circular (because I feel, just because) or to name characteristics such as 'I feel feminine which is gentle, kind, motherly, wearing lipstick' etc. And we know that femininity is not part of what makes a woman.
If you can't say any key characteristics which make up a category, then that category does not exist. Therefore 'women' would not exist. If women do not exist then you can't argue you are one.
My other half says it is possible to identify as something without defining it, if you say what you are not.
'I feel like a woman because I do not feel like a man or masculine'.
But sure you then just get into the same loop- what is a man?
Thoughts?
