I think you skipped one part. I haven't posted much here in years so just so you know, I'm all for supporting Ukraine.
That being said, there is very little discussion on Twitter. Garry Kasparov would be ratio'd in about 5 minutes if he'd ever make a statement like "Maybe it's time to negotiate" ( Not that he'd ever do that because he wants Putin gone).
So yes, you're right about the alt right and far left but you're missing the were supposed to be middle ground but now seem to be uncompromising to even discuss anything but absolute surrender by Russia.
