On some sites, folks will up-vote things that they agree with and down-vote things that they disagree with. Or, sometimes up-votes are a mode of expressing emotional-support or communal-acceptance. Maybe that's what you're used to? Here, folks tend to prefer substance. They'll often down-vote you even if you express a view that they agree with if your comment doesn't contribute something worth reading. And they might up-vote your comment, even if they disagree, if it was interesting to have read. This is more of a place to exchange ideas than find validation. You're not being rejected on a personal level -- down-votes aren't personal attacks. And people don't necessarily disagree with you, either.
