About disagreements on the site...

I've notice some bickering and hurt feelings on o few of the threads lately. I happen to be one of those who feel there is nothing wrong with disagreement or debate, as long as it doesn't resort to name calling or personal attacks.
It seems to me if all we hear from each other are validations of our own opinions then there is no point in even asking a question, it is hearing different points of view, even those we don't agree with, that allows us to learn from each other.
