i think it's more about putin than russia. he is anti-democrat, anti-liberal, nationalist, authoritarian, has tried to build a strong white male image whose health is more than fine for his age. does it ring a bell? i can see why many maga dudes idolized him way before the war
it's also a polarized world, you're either camp black or camp white, be it music, sports, science or politics. there are no middle grounds. you're anti biden? putin is anti biden too. and trump said that with him in charge there would be no war. and there's those biden ties with ukraine. and putin is anti ukraine, so once again, he's anti biden. so you're best buddies with putin for life ¯\_(ツ)_/¯
might be wrong of course. either way, local right wing people also root for russia for similar reasons. they have the memory of a goldfish and forgot how it was to live in the eastern block under the soviets. and of course still call the european liberals commies. like putin himself didn't adore the ussr ffs
