Just discovered I've recently been unfriended by someone who is not at all gender critical & has previously argued the toss on a few of my threads about TRAs.
Someone else did the same over a year ago (although without any arguments - just cut off)
I was unfriended by at least 3 people for critical posts about M Thatch when she died, & by 1 for criticising anti-Corbyn MPs.
These are all people I had had plenty of amiable exchanges with on other topics, & felt able to just ignore when they posted stuff I disagreed with.
It seems a shame that in each case one contentious subject has apparently outweighed everything else
