'cis-het' and therefore lying and ineligible
This is it - I'm het, but by their very own definitions I'm not 'cis'. Unfortunately I don't live in the UK right now, so I didn't fill it in.
Perhaps they need to be a bit more clear on their definitions before they get upset.
I can define woman, sex, gender, female etc. in clear, independently observable ways. As soon as they can I'll be happy to let them know whether I'm 'cis' or 'trans' by those definitions, but so far, all I have is
'referring or relating to people whose sense of personal identity and gender does not correspond with their birth sex'
and gender being
'the state of being male or female (typically used with reference to social and cultural differences rather than biological ones).'
I certainly don't identify with many of the social and cultural expectations of a woman in UK society, therefore, by any trans measure, I'm trans.
Since I'm a GC feminist, I actually just think I'm a woman with a personality.
