People also don't realize that each word carries a connotation, and even if the message doesn't have any verbal clues, it has clues in the vocabulary. If you use aggressive words, like I do sometimes, you can really offend without meaning to.
This is true, but a lot of the offense taken seems to be a consequence of some readers expecting a homogenized language and having no respect for grammatical flourishes that make an individual's written style as distinct as their spoken style. I'll occasionally write in an elevated tone simply because I like using uncommon or beautiful words (as I put it to someone who once misread me - I like throwing in $5 words whenever possible because my vocabulary isn't poor)...to someone who hasn't read me enough to realize it's just my style, I can easily come off as a prick because of this. I don't mind so much, though...in the sea of disemvoweled tripe that is the vast majority of internet speak, there must be a few beacons of readability
