The first thing I did was question whether or not you knew the actually definition of the word you are trying to use, and which was evidently being used incorrectly. There's nothing xenophobic about correcting people's use of language, especially when they are making claims that are scientifically proven to be untrue. If I had said something like "you big idiot can't even understand English" that would be pretty xenophobic, but we both know that's not what happened. I simply asked whether or not you actually understood what you were saying, and you responded by getting upset and defensive and then start insulting me.

You remind me of those people that shout "racism" or "sexism" at anything they find unfair, regardless of whether or not anything racist or sexist even happened.

Seriously, find me any quote at all that I've said here that implies not knowing English is a bad or shameful thing. Nowhere did I suggest there was anything wrong with you not understanding something. I'm just simply pointing out that your lack of understanding means that your original comment is factually incorrect.
