I think it's more that it's arrogant to keep an opinion even when presented with evidence that it's wrong - like thinking you know better than anyone else and refusing to listen.

I don't think you do that very often, for the record. You're usually pretty open to other ideas.

Well, I don't have too many lines compared to most people... I tend to figure everyone has the right to decide for themselves what they do. Unless it affects me personally, why should I care or try to stop them?
