On one hand, sure we could all do with some rules on civility.
However, people who support Russian claim to Ukrainian territory (not those that support and end to suffering, there's some nuance there) are, to me, despicable. In the same vein that we must not tolerate intolerance, I don't see that position as a viable position to take.
I'm all for vitriol when pointed at a handful of pre-selected targets. You can hate nazis, you can hate pro-russian pundits, and you can hate the guy who sold Ea-Nasir that bad quality copper in 1750 b.c.
