Nazi's bad. Now, let's see you condemn the Ukrainian Nazis. I'll wait.
Nazi, communist ans socialist organisations are authorized to exist in most countries and that includes USA, Russia, Ukraine. As long as they are not doing unlawful things they obviously can’t be condemned.
However, if any of those groups help a government (in this case the Kremlin) to invade another county and annexe its territories - that’s in direct violation of international law, and is causing massive destruction and death for the victim of that invasion. The victim here being obviously Ukraine.
Thus, in such a scenario only the agressive attacking Nazis and Commies should be condemned.
A defender has a right to self defense: such a defender can be of any color, religion, political affiliation, male or female.
No problem whatsoever.
I’m still waiting to know if you condemn the embedded Nazis, commies and “others” in the Russian army attacking and annexing Ukrainian regions by force - in violation to international law?
