I agree with your points, but it's worth noting that to non-native English speakers, certain words, in particular profanity, don't have the same meaning/impact that they do for native speakers. Just the same as if you uttered a string of, say, Hungarian expletives at the dinner table with your family (assuming you aren't Hungarian speakers), it would not be considered terribly offensive, most likely.
