What is Gender then? Enlighten me?
I already posted this upthread but you're not reading the responses properly at all. I can tell by your response to my previous post which bears no relation to what I actually said.
Gender are the roles and expectations that a particular society holds towards the two sexes. These can and have obviously varied across time and region but in general gender roles are oppressive to women, and often to men who don't conform to stereotype.
That is why asking someone to agree that they are cisgender is asking them to say they agree with the gender norms of a society, ie buy into their own oppression.
I have never understood gender as an identity. I certainly don't have one.
You seem to believe in gender identity as some sort of material reality which is why you are struggling to understand what people are saying to you. If you accept that it's not a concept everyone believes, things might be clearer to you.
