Socialism only comes from the left. By definition.
The Communist and the Fascist both practice, no demanded extreme social control and are therefore the same no matter how many angels you think can dance on the head of a pin.
You remind me of that Star Trek episode, “Let That Be Your Last Battlefield”, where each antagonist is jet black on one side of his body and snow white on the other side, yet because for each it was the opposite side, neither of them could understand that they were the same fools to us sane people. Tell that to the Gruppenfuhrer.
And remember, Stalin also murdered Jews. That Jewish persecution continued until present times. My next door neighbors are Russian Refuseniks who thankfully were able to finally leave that hell hole and come here to become American Citizens.
