Its funny to see how liberal Americans (I'm might be wrong but I assume you would call yourself that?) seem to have adopted a kind of reverse-patriotism where everything non-american is always better and foreign countries are looked upon with rose-tinted views.

I am from central Europe, but have travelled in America and have family over there too, I can tell you that women being attracted to loud, boorish, extroverts its not at all specific to white Americans. This is pretty much a universal human trait.

Its also interesting that you say that immigrants in America are not like that at all? Because in my experience, at least in the black and hispanic communities - they have far more of a macho culture than most white Americans do.
