I haven't got the sources at hand but likely another hexbear user will be by soon to drop some sources on modern Russian anti-fascist prosecution in their country. Don't get me wrong, I don't think being a leftist in Russia is a cakewalk, but they're not black vanning communists like Ukraine is. They're also not putting up statues and waxing poetic about explicit antisemitic fascists and nazis like the Banderite government of Ukraine does.

Just to comment on the "don't fight Russia" point, consider the situation: Russia is invading with one of their goals being de-Nazification, and if you live in or near Ukraine and are a leftist you surely know that Ukraine is basically the beating heart of Europe's neo-Nazi problem. A sober look at the Ukrainian military and performance as compared to Russia leads to the inevitable conclusion that if Russia really wants to take some land in Ukraine, they can and will. Does it really make sense to fight shoulder to shoulder with the nazis who hated you before, hate you now, and will kill you or push you into a minefield at the first opportunity? That land is going to be owned by foreign capitalists or Russia, there's nothing you can do to stop that. If you have to pick up weapons, might as well aid Russia and help them remove the Nazi rot from your country - particularly when Russia's never had any demonstrable interest in controlling all of Ukraine. All they ever wanted was no NATO membership and an end to the civil war.
