People make a big deal about not caring what anyone thinks, and then they're spiteful dolts over the silliest things. Many are basically admitting their (own) opinions are moronic.

I care what people think, and that's in part because my thoughts are worth something; I want people to care what I think in turn.

It isn't that *I* think it, or that I *think* it, but that I have put a lot of care into the thought. That is why I think others should care, and it is why I care.
