This is one that political scientists have yet to fathom.
Just how is it so many left-wing women apparently became far-right in such a short time? And yet they don't spout or publish far-right material, there's no evidence that they are funded by the far right, and indeed the 'far-right' in the UK doesn't rightly exist to any substantial degree. It's going to be a struggle to find any 'T2rfs' in Combat 18.
A more likely explanation is that the effort to try to associate those opposed to the efforts to remove women-and-girls safeguarding protections and those opposed to 'transing-away-the-gay' plus those opposed to US-based BigPharma (which profits hugely from the New Homophobia movement) are labelled as 'far-right' in an effort to split the Left and try to limit the damage that could be inflicted on US corporations.
The LibDems took a huge donation from BigPharma and this could explain their commitment. Many who profess to be 'leftist' in the US and UK are hugely pro-corporate and dedicated to globalism; a great example being the rioting in Portland and Seattle in 2020 which left corporate headquarters offices relatively untouched, but saw thousands of small businesses with insufficient insurance (often Black-owned) torched and forced-out-of-business.
Big global corporations, particularly the polluting ones, get a pretty easy ride from the 'modern' Left these days. Even so-called climate protesters will happily glue themselves to a painting in a national art gallery rather than confront the key shareholders of strip-mining companies or those building coal-fired power stations.
We might living in times when the Left in the US and UK are so well aligned with the needs of BigPharma and global corporate concerns that it shouldn't come as a surprise when left-leaning women get accused of being 'fascists' or 'literal Nazi's' in an effort to try to get them to shut-up.
