It is quite a dilemma. It depends on the number already voted. For example, if a post I don't agree with is quite rational and has low votes I up-vote. But if it already has some votes I leave it there... Unless it has a double digit number and the other side is much lower, then sometimes I down-vote (and feel almost guilty about it.) Many times I agree with someone but their post is incomplete or has a part that isn't good, then the replies tend to say the whole side is invalid because of that... It's very hard for me to pick what to vote specially when groupthink or fanboys back either side (yes, including my side.) There isn't a perfect way without granularity on votes.
