The ability to reason, debate, and form conclusions is what life is all about. Socrates said "A life unexamined is not worth living." Sometimes you examine more of yourself when you hear differing opinions; I know I have been urged to rethink some of my very set ideas as a result of Cellar debates.
And I've certainly seen more detestable habits, but I won't go there.
By the way, Dale Carnegie also said "Fear not those who argue but those who dodge."
