Yes, bad things happened in the #SovietUnion. Nobody denies that and nobody excuses that.
What you have to understand is that the Soviet Union was under constant #imperialist sabotage. Naturally, there were some excesses, just like under #capitalism bad things happen all the time.
When bad things happen under #socialism, it's always an indictment of the #socialist mode of production. Yet, when bad things occur under #capitalism, no one uses that same logic of thinking to condemn capitalism. Or if they do, they're brainwashed into thinking it's just how things are.

Stick around for about a day. You will see far, FAR more people complaining about capitalism than you might imagine. A couple of them even go so far as to try to construct coherent complaints. A VERY few.
