I disagree with that, I have had expressed 'extreme' opinions in this forum but I kept it civil, positive, and all I got hit with was to lose some 'karma points', and even the comments 'slapping me' were positive and I learned from the dialogue.
I am not perfect, but who is?
I believe in this forum we value open mindness and a fair dialogue. I don't like agreeing with everyone on everything, that would make a very boring and unproductive forum.
