The list is obviously longer than just ultra nationalists, but the anti fascist weren't exactly fighting for some international community (eg: partisans in Italy). They would fight the fascists and if invaded by others, they would fight them too. They were fighting for themselves and to liberate their country.
The point, which maybe wasn't clear, is that it's those with more "extreme" views that stand up, not the average person that wants to run away. The early groups in Ukraine after Russia invaded were not just neo nazis. They even had groups of anarchists fighting in the east.
> For some reason none of those Azov fighters that rubbed bacon on their bullets because the Chechens were coming are so brave and loud now. I wonder what happened
Mostly dead, I assume. For all I care, they can all disappear. Them and the "ruscists".
But you missed the point here too... How many units were named after Azov before and after the siege? Do you think it's a good idea to create conditions for them to be "glorified" since they were sacrificing themselves (whether you agree or not is besides the point) if the intention is to denazify a country?
