I think a lot of people use it in a wrong way... just because u dont agree with somebody opinion doesn't mean its wrong. its just an opinion. I just use downvotes when people are rude or just making a bad troll or something like that. We are all diferent but he all deserve equal respect
I up vote almost everyone. I only downvote someone if they're really rude. If they explain their opinion well, I up vote even if I don't agree. Asking someone to give an opinion and then disliking it because you slant agree is really immature in my opinion.
