It's funny, it used to be all the hard-left-wing people who were incapable of getting on with each other, and who would form tentative alliances with each other only to fall out five minutes later, having huge strops and accusing everyone else of being evil, bigoted etc. (People's Front of Judea stuff, call-out culture, purity spirals...)
Now it looks like the hard-right-wing people are doing the same thing - hair-trigger offence-taking reflex, purity tests, constant whinging demands.
It's all rather exciting to watch.
