Socialism is the process of building communism. It is a transitional phase. There is still a class struggle, but the state is already in the hands of the working class. You cannot build socialism. You can either build communism or go back to capitalism. Building socialism is like being half pregnant. Building socialism and class peace is a fairy tale for the poor.
"I know how well communism pairs with genocide like the steak and wine..." The Communists never carried out genocides. If you mean the Red Terror, it was a backlash of White Terror under extremely difficult conditions of intervention and civil war. The number of victims of these measures is usually grossly overstated. The capitalists, on the other hand, have no conscience at all. They are willing to destroy millions of people for the sake of their power and their profit.
If you want to delve into this subject, read the classics: Marx, Engels, Lenin, Stalin, Mao. Trotsky is a traitor. I suggest you start with someone else. Engels, for example. He writes in an interesting, lucid, humorous way.
All Marxists study philosophy, history, economics as a basis. By the way, this subject is much easier and interesting than it seems. Especially if one does not study alone, but in a Marxist circle.
