I wouldn't get too excited, they tweeted the other day that getting rid of sexual protections from the equality act wouldn't harm anyone because sex is a social construct.At least he admits he isn't a woman ...
There are quite a few trans-identified men that also claim to be another race. There is a well known white guy who claims he is a Filipina woman, and an entire group of white men who claim to be not just Muslim women but South Asian/Middle Eastern Muslim women!
On the black identity thing...I assume the Greens might have a black woman or POC group. Maybe they want access to that?
