Through my sarcasm I was trying to convey the often imperialistic (and in my opinion useless douchebaggery) view we tend to take on certain matters and people, which, I believe, hinders communication and progress in general. It's not just a language barrier, it's a cultural barrier. One that exists even between people who speak the same language. (Don't know if the social media movie scene with Zuckerburg being reprimanded by Harvard was based on real events or pure fantasy, but that's a good example)
So he ignored some squiggly red lines, maybe his command of English is marginal. Maybe he's worried about bullets possibly flying over his head in a few minutes or in a situation that many of us in the west couldn't fathom. I've had to communicate in Spanish before and I know I probably slaughtered the grammar, spelling and more, but at that time I was trying to convey an important message. Fortunately the people I was speaking with were very kind and patient. They listened and somehow understood the sentences and symbols I had cobbled together.
We have this whole attitude that if someone doesn't fit our cultural context in language or behavior, their are somehow inferior, is absolute BS. I have seen programmers with a an accent perceived as being "dumb", while in fact they were far better than their peers. I myself have been subjected to this type of bias, when I forgot to follow some proper decorum somewhere, simply because I was broke and had more important things on my mind. This is typical of out-of-touch monolithic institutions and the type of thinking that goes with it. It's outright absurd and funny, just like my sarcastic comment :)
