[Fnoord]

When someone who's native English complains about my English (and I've been complimented about it throughout my life, it being the only secondary language I more or less (feel like) I can control), I say: how's the quality of your secondary language? My primary language is Dutch, not English.

Same with anyone in Europe I meet who speaks English (except for Ireland and UK): its their secondary language. So when I hear someone who's native Spanish speak English, I have compassion and appreciate their effort. For Dutch not so much. Its a relatively small and nowadays insignificant language. We grow up with English, its normal to speak, read, and comprehend English.

What you shouldn't forget is that you're generalizing. Americans refers to people of USA in this context, and USA is a large country, with a lot of cultural backgrounds, and various levels of intelligence. That goes for any country, but this country specifically has over 200 million people, and last 20 years it has become polarized as hell.
