Book, STFU. Nah, jokes, I just can't remember anything of value you've said in order to comment on it... Jokes again
Okay, musn't troll. The ethnocentric card was stupid; his point was that the IMPLICATIONS of the features page were as he stated originally, and missing that is either a logical error (harsh) or more likely (and politely) a simple linguistic misunderstanding. As the son of a multi-lingual translator (14 languages, last I checked), this was the FIRST thing I was taught to expect when trying my languages out with mother-tongue speakers. It's not insulting, it's a fact of life. Just like I don't understand German/French/Scandinavian humour and everyone thinks the Turkish are creepy; translations don't often capture sentiments and implications. Hell, even the difference between US and UK english dialects can be insurmountable for native speakers! Simple anthropology/linguistics studies will tell you all you need to know that there was no ethnocentrism here; merely politeness.
