Thats literally complete bullshit. Everything you know about the USSR is more or less propaganda. But even if we suppose its true, capitalism kills hundreds of millions a YEAR globally when you look at the effects of extreme poverty, food insecurity, lack of housing, untreated medical conditions etc.
All of which could be easily avoided and WOULD be avoided in a socialist world, even in the USSR such things were barely existent if at all.
Imperialism is also inherent to capitalism, look at how many millions died in Vietnam, Korea, Cambodia, Laos, Afghanistan, Iraq, Iran, Pakistan, Somalia, Haiti, El Salvador, Ecuador, Nicaragua, Cuba (American terrorism), Guatemala, Argentina, Palestine... Literally my hand is hurting writing this list and it just goes OON AND OON AND OON.
So to summarize, communism was by far the more favorable system world the world. American imperialism / capitalism is absolutely destroying not only human lives but our entire planet with it. Its absolutely maddening.
Even if it was 240 million, it was inherently more fair and just system where at least the intention was to HELP one another and to build a equal and sustainable society. Now everything exists to create more wealth, to create even more wealth to make more we-...
This is the truth.
