DISCLAIMER: My character (Llavi) is not rude/nasty/bitchy/dickerly/etc toward anyone who is "American". I specifically put that he is slightly more apprehensive of them. Key word being apprehensive: nervous or uneasy in certain situations, typically fearful that something bad might happen. 

As for the TV Gringos, I took the time to specify that mentally he is more critical. In that, he analyzes them as individuals more than he might normally. (I.E. if they show an unflattering side he will [slightly] chalk it up to their upbringing).

Please don't take liberal assumptions of him.
