Criticism is futile because it puts a person on the defensive
and usually makes him strive to justify himself.
Criticism is dangerous, because it wounds a person’s
precious pride, hurts his sense of importance, and
arouses resentment.
Are you serious? A forum can or should have a lot of diversities. There will be sth. you like, something you don't like. People express their emotions and thoughts, nothing wrong with that. Everyone should be mature enough to take what they need.
