This is the crux of it. For some, women's rights is now about trans, and only about trans. And if you admit to seeing the wider picture, you're an MRA, a TRA or a man. Now that's stifling debate.
These threads aren't a bunch of people Labour fangirling. They contain voters from across the political spectrum. We talk about wider politics all the time. Right now there's an election and so that affects the discussion. After the election, the focus will widen again - expect plenty of criticism of the new government.
