My greatest weakness in this community is probably that I against my will partly believe that most americans are stupid due to lack of general education and political propaganda.

Have you considered the effect of selection? From USA, you usually hear about the stupid stuff, because that's what makes interesting news. (Also, exaggerating all the bad things from the "decadent West" has a long tradition in Russian propaganda.) From your own country, you spend most time with your circle of educated people.
