you gotta understand something about tankies: they think that's a good thing

You do know, that communism and authoritarianism are two completely different things? Communism by itself is neither authoriatarian, or democratic. A communist world aims at dissolving all borders to achieve global equality without any form of higher governance. This of course is something thats quite unlikely to ever happen. A totalitarian regieme is directly contradictary to the pure idea of communism, which is that everyone should have the freedom to support (or not support) society. Any form of violence (no matter what type of violence) to force people into a set system is therefore contradictory to these ideas. Just because we didnt see very good examples of communism (maybe cuba, but I dont know that much about it, so I cant really judge) this doesnt mean, that communism itself is an inherently dysunctional and bad system.

Also, we have seen much more violence being emitted from capitalistic states, even if they claim to care about human rights. Every year the EU pays quite a significant amount of money to Lybia, so that their coast guard stops refugees crossing the mediterranian sea, causing hundreds of deaths and trapping those who get "rescued" by the coast guard in a subhuman system, where rape and torture are normalised.

This does not mean to invalidate the harm done by self proclaimed communist regiemes, but to show that shitty practices are done by all kinds of different people.

In the early 1900s the workers of the world were beginning to build the framework for the democratic collectivization of resources and labour. Elites considered this such a severe threat that they were organizing their own conferences on how to deal with it. This was stopped in most countries with one of two methods: concessions (like The New Deal) or fascism. Welfare or fear-mongering austerity politics.

To put this another way: some capitalists conspired to promote and ultimately install fascist authoritarians to fight socialism because it was in their class interests to do so. The various banana republics and other economic colonies of imperialist nations? Installed by capitalists. The forever wars that no one even wants? Believe it or not, also capitalists. These are not the moves made by freedom-loving people lol.

So I guess I should ask you: where are you consuming your propaganda from?

The US is the most capitalist and the greatest abject failure.

Do not confuse capitalism with commerce. Commerce improves lives; capitalism seeks to destroy them for personal gain.
