yeesh, that’s pretty nuts. even if Ukraine has far-right groups (and they do), that’s not anywhere near the same as saying they are exporting Nazism (whatever that means).
Russians conveniently forget that they too have a Nazi problem.
The whole thing is beyond insane. They have repurposed "Nazi" to mean "anyone the regime doesn't like." While actually behaving as Nazis themselves. They are playing very close to Hitler's playbook.
Well, it is complicated.
Yes, there are neo-Nazi groups in both Ukraine and Russia. One of the more well known examples in Ukraine is the Azov Battalion which was integrated into the Ukrainian Armed Forces under, I believe, Poroshenko. Ironically, that group was founded in a region of Ukraine predominantly populated by ethnic Russians, but again, Russia will just conveniently ignore that.
The other thing is given Poroshenko's politics calling him a neo-Nazi would probably not be too far off the cuff, however, he's been out of power for a few years now. Again Russians ignore this.
During WWII you had a Ukrainian fascist, nationalist, and Nazi-collaborator named Stepan Bandera. Despite his actual Nazi political leanings, he is sometimes controversially celebrated as a national hero in Ukraine (assassinated in the 1950s by the KGB I believe); sort of like either George Washington or Abraham Lincoln, or Lance Armstrong before we knew about the steroids. This is because he had such a dream of an "independent Ukraine" and so in the mid-2000s the Ukrainian president at the time, Yushchenko from the Orange Revolution, posthumously awarded Bandera the Hero of Ukraine. That award was revoked after protests from Russia, Poland, Israel, the USA, the EU and a few others (the man killed thousands of Poles and Jews while collaborating with the Nazis). However, the Poroshenko government tried to re-award him the award but it didn't make it through Ukrainian parliament. Again, Russians ignore the fact that the award was revoked.
Russia and Russians see Ukraine as a brother country similar to probably either the USA and Canada or Australia and New Zealand. Ukraine and Ukrainians do not share this view. This is because after the fall of the Rus to the Mongols in the 13th century, most everything from Kiev to Lvov in today's Ukrainian borders would be ruled by Poland until the Partitions of Poland under Catherine the Great. Eastern and Southern Ukraine would mostly be under either the Muslims or the Mongols; the Russians didn't come in until Catherine the Great. But again, Russians ignore these facts.
Ukrainians have had a fairly militant view towards Russians for a long time because of how Russians treated non-Russians not only during the Empire, but also the Soviet Union. Are Ukrainians wrong for being attracted to Nazism? Absolutely. Can we blame them entirely for having gone to such an extremist view? Not entirely.
Russians, as a people, have never been able to admit their own shortcomings and Putin is a great example of what that has evolved into. Sure, we have a lot of Orthodox saint who are Russian and are great examples for all of us. However, if Russians' attitude towards Ukraine is any indication than clearly their not being told the full story of those saints which they revere so much.
EDIT to add: While not excusing Nazi, fascist, Communist, nor any other extremist group; I guarantee you that if the United States were to be invaded and occupied by some other foreign nation, like what Ukraine is going through now, among the first to fight said invaders would likely be our own crazies like the Proud Boys and the KKK.
