I wouldn't worry too much about it. There's no way Labour can win the election so once it's over in three weeks the manifesto will be meaningless. It does indicate they have listened and it is encouraging they do actually call women women and refer to single-sex spaces.
The most encouraging thing is that the Tories, who were in power when the election was called and are highly likely to remain in power, have rowed back on gender self ID.
However I'm pleased there is a differentiation between Labour and the Lib Dems and Greens. It does demonstrate they've listened even if they have fudged it a bit.
I would very much like to vote Labour but I can't due to the antisemitism it has allowed to flourish. I'm not keen on voting Lib Dem due to their stupid policies on gender and refusal to recognise women's sex-based rights. I'm still in a quandary as to who to vote for.
I am basically having to decide which matters most to me - my feminism or being Jewish!
