Looks like someone forgot to put on their smiley face this morning. Everyone, let's have a big group hug for piezoman before we send him off to Siberia for re-education!
You know, the world over, people just want a better life. To provide more completely for their families. Few set out to make it all worse.
Then we have various philosophies about how to accomplish that universally sought goal, a better life. And with all those systems, a narrow few who hold the most power invariably sell everyone else out to enrich themselves. This happens equally in communism or capitalism. They manipulate people through propaganda in order to further their own power and wealth. In that regard the track record is clear, on the level of exploitation, Marxism and Capitalism have much in common.
You see, the problem isn't the "ism". The problem is human greed, violence, and general stupidity. And that is a human condition found equally no matter to which philosophical wagon you hitch your horse.
The truth is that if the humans involved were enlightened and awake, any economic of political system could work equally well. Capitalism, communism, socialism, totalitarian, fascist, take your pick - if the human heart is pure, any of those would work.
But the human heart is troubled. No form of legislation can force the fragile wayward chimpanzee we call human to act in a pure way.
Marxist are people too. They have the same hopes and dreams as everyone else. They simply have a different way of approaching things, and a different set of thugs running the show.
Human confusion is the core issue. Political ideology is entirely tangential.
But hatred always needs an enemy for fuel. Something has to be the enemy. That itself is a limited level of consciousness.
I visited the Soviet Union before it fell. I remember complete strangers taking me on a long ride in a fabulous horse drawn carriage through the streets of Leningrad. They were just people happy to see a foreigner. Nice people - they heard me speaking english and said "please get in", and we had dinner at their house afterwards. And that's how I became a spy for the Soviet Union, sending hundreds of thousands of documents via a KGB contact who was coincidentally named piezoman (ok, that spy part is fake news, but it did make the story more interesting).

Don't get me wrong, the Soviet Union was an utter mess, but the people were kind. And when we have the awareness to look beyond the outer shell of ideology, we will see that all regular people just want a peaceful life. The Russians love their children too.
Just like you.
Debate ideology to your heart's content. But please, don't waste time hating anything. Hatred is far bigger problem than any political ideology.
It's worth noting that monastic orders across the world have, for centuries, lived in a fairly communistic manner - with most things held communally. I'm not advocating for that, it's just an observation.
