While they certainly exist, the Communist Party of Britain thankfully is not among them: https://archive.ph/F1Ow4

The Communist Party of Britain affirmed that it supports transgender people’s right to “live equal, full and meaningful lives” after J.K. Rowling, almost as well known at this point for her hatred of trans women as for penning the mega-popular Harry Potter series, expressed tacit support for its candidates. On Saturday, Rowling encouraged her social media followers to vote Communist, a move made in response to the anti-trans feminist group For Women Scotland tweeting that a party spokesperson had told them it stood “in support of [recognizing] the nature of biological sex.” A day later, a statement was released on the party’s official X account clarifying the matter. “For avoidance of doubt, the Communist Party supports the right of trans people to medically transition, to have access to healthcare and live equal, full and meaningful lives, socially, economically and politically,” it said. “We believe that such liberation will only be possible under socialism.” Rowling’s blessing, likely now to be rescinded, came after she published an op-ed in The Times of London on Friday disavowing the Labour Party over its support for trans rights.
