So that way if someone disagrees with you they would have to say why or nothing at all. A ton of people make valid points in their opinions but they get voted down. Sometimes I'd like to know why they feel that way.
No. I feel like it doesn't matter if anyone agrees or disagrees with your opinion...its YOUR Opinion. Other users should have the right to disagree by down voting, or agree by upvoting. Either way, it doesn't matter because you dont get points for up votes, or points deducted for down votes. So it essentially just doesn't really make a difference.
Also, there are people here who hate on users...just to hate. I can't tell you how many times I have been down voted here. Users on the old GAG site would follow users to every single question, just to down vote their responses. Or people here jump on the bandwagon and down vote people for no reason, or just because they want to be confrontational and crazy. It just shows that some folks here do not have a life. I believe GAG has hidden the up votes and down voted too discourage users from bandwagon votes.
