Slightly on a tangent.
I had an email from Labour letting me know that if I self identify as disabled I can vote for the disabled members representative. Maybe they are for self identifying into any of the protected characteristics... 
I can’t say I am a life long committed Labour supporter because I have voted Green and LibDem in the past too (I wouldn’t now) but in recent years I’d been thinking that Labour really are the only left wing party with any chance of getting into government and I joined to support them.
I followed the leadership contest with interest not sure at first who I wanted to vote for and then the trans pledges changed everything for me. I had been blissfully ignorant of the TWAW thing in Labour up to that point. I looked up the supposed hate groups WPUK and LGB Alliance and found my way here thanks to Maya Forstater’s recommendation somewhere.
I have been hanging on waiting for Keir to come out in favour of women’s rights, reality and safeguarding. Feels like it is nearly time to jump ship. The SDP looks like a party I could vote for but I have never seen them on a ballot paper yet.
I live in a safe seat anyway (Tory) so my vote is meaningless, in large part that is what actually prompted me to join Labour. I am not really a political party joining kind of person... but I don’t feel that I have much input into democracy by voting in FPTP system. I always turn out to vote anyway on principle.
Just what is the point of any of the protected characteristics without sensible, fact based gate keeping? If something is protected it generally has a boundary around it.
