I still do not understand how this argument works. Why is it that people only seem to be offended at mediocre vocabulary when 'profanity' is involved? If, as you state, emotionally charged speech without profanity is difficult, why should we become offended when people are unable to achieve it? I don't think anybody goes to technical talks to appreciate high grade word-smithing. I honestly believe this is an instance of generally rational people becoming offended for a reason they don't quite understand, and inventing a theory to explain the data.
