I've been thinking about this a lot. Trans ideology likes to split people into cis or trans, making a clear binary. Either you identify as the 'gender assigned at birth' or you identify with a different gender, making you 'cis'.
Like many (most?) feminists, I reject gender completely. I do not feel a gendered sense of self, I do not want others to treat me as a certain gender, I do not have preferred pronouns.
In order to fight trans ideology, I think we need to show the trans vs cis binary for the nonsense that it is. We need to show that there are other ways to exist outside this binary. You can be agender or possibly antigender. Ungendered? What do you think?
