It's fairly obvious you arent well read on socialism. The way you think about history, development of society and its transformations are clearly incorrect given the other stuff you've posted (for example, you don't understand how propaganda works). So we don't need to explore very much further.

You are not taught how to grapple with those topics properly in America and in fact are taught an older, outdated manner that is instilled into you since birth by everyday interaction with parents, friends, education, media, the list goes on. This is the true nature of propaganda.

What you should be concerned with is the scientific interpretation of history, since growing up in America, you do not learn this but rather the ideological one that, even when you say you criticize the US, often simply ends up supporting the US, who has been the biggest barrier in modern times to historical progress.

Have a good day and don't take it personally. I'd wager 90%+ of us here started out like you.
