That sir, I believe, is the incorrect way to do it. I may believe in capitalism, and I may believe that communism is wrong and someone who supports it is misinformed. But that should not mean that I downvote all comments extolling the merits of communism. I try to keep in mind that what the commentor wrote is his/her opinion and if that comment is well-written and adds value to the discussion, it should be upvoted and encouraged.

Long story short, comments that add value, contribute positively to discussion and are insightful need to be encouraged. My stand on the topic should have no bearing.

Too many people downvote people that they disagree with which is the downfall of a karma based system. What if you disagree, but they are right? Why do you dislike the fact that someone may have an opinion that differs from yours?

Downvoting people you disagree with implies that you are always right. I bow down to your perfection.

You forgot to read the part where he mentioned downvoting because the information was wrong or misinformed. The same way I'll get downvoted if I furiously debated that an apple's color is always blue.

No, because he THOUGHT it was wrong or misinformed. Large difference between something being wrong and him thinking it is wrong -- unless he is always right.

If something is factually correct, and he disagrees with it and thinks it is wrong, it gets a downvote. I was actually more amused that he got upvotes as it sort of reinforces the point I was trying to make.

By his logic, if we disagree with his point, we should downvote him, whether his opinion has merit or not.
