I did see something about this on Jewish Twitter - there are indeed nutters on the far right who attack Jews as being behind everything they dislike on the far left, including trans rights. It's part of the same far right movement that shoots Jews in synagogues because they think we are plotting to fill the western world with Muslims (no, me neither).
And that believes all Jews are behind gay 'propaganda' to undermine western civilisation.
The irony that Owen Jones, that great friend of anti-Semites everywhere, is now pretending to give a shit about Jews when it's convenient for him, is overwhelming.
There is a moral there, that those on the far right who oppose trans rights are not automatically on our side as GC feminists, and we should be careful who we ally with. Ultimately, allying with people who query the overreach of trans rights but also hate Jews/black people/LGB people is not actually in our own interests and lays us open to being called out for the sins of others.
