I read Cunc as commenting only on your histrionic style. In your first sentence that I quote above, you characterize his complaints as "nonsense". There are people and cultures for whom that alone is mortally offensive, and yet you toss it off as if you think everybody will just automatically agree with you.
Yes the issue is often more one of attitude rather than substance. Really it comes down to respect. Dissing folks is hazardous.
