Interesting since there are plenty of other places in the world where English is the native language, and yet you're assuming this hypothetical ugly character is American.

Jumping on people for their presumed nationality doesn't look so good either.

And no, I'm not American. And English is not my native language either. 

 I am American and I'm talking to other Americans (and they know who they are), so take your sorry midwit ass to your own intellectual weight class, buddy. 

 Yes, I can certainly sense the palpable hatred you have for your countryfolk, as well as your rude, smug superior arrogance.

Ironically, fitting the American stereotype pretty well indeed.

And you're right, I'll remain in my own intellectual weight class. Above the rude American woman.
