When you're fighting an invasion of your country, its a bad time to quibble about the ideological purity of the other people on your side of the line.<p>It really is possible to find shared goals and cooperate on achieving them with people who do not <i>totally</i> agree with you. Once the immediate threat is addressed, those people might be the next item on the agenda; but this is "stand together or fall separately" territory.
Heck, in NL we have them in Parliament. Let's hope Putin doesn't come here to denazify us. On top of that: Russia most likely has more Neo Nazi's in Moscow than in all of Ukraine, this is just one giant distraction from what matters: that Russia has invaded another sovereign European country.
