Russia and nazi Germany formed a pact at the onset of WWII, due to shared interests. Fact. This was after the fascist-socialist battles in Europe of the years before. 

The "Union of Soviet Socialist Republics" adhered to Stalinism. Stalinism was socialism, most certainly. It was a centralized socialist government. Wherever socialist countries exist, free speech rights and dissent aren't tolerated. For many who do wish to exercise what we value as Americans results in imprisonment or demise for their opposition to socialist ideology. There really is no individual liberty and freedom, as those rights are eroded.

The fascists of the far right should be opposed, but not with violence and un-American activities, if you know what I mean? They are hardly the GOP, just as the antifa and socialist extremists of the left are not the Dem party as a whole. They aren't worthy of praise either.
