Direct quote from

"... nobody has the right to deny the worth of someone's work just because they can't see it. I know everyone is free to come up with their own opinions. That's all well and good, but there is no need to pointlessly bring down people who have opinions different from your own. I'm not just defending myself here - I'm speaking for everyone who has had this happen to them.
... Before you use freedom of speech as an excuse, take note that something of equal importance is the sense of common decency. You're certainly not going to change people's minds by making yourself look like a rude, bitter, popularity-crazed prick. You're much better off using your time doing something that's actually productive if you truly care about the community."
