Fair enough I suppose. I don't agree that anyone has the right to downvote something just because they disagree with it; as I would hope they would instead provide a reason for that disagreement, but it's not my site, so not my rules.
But I still don't agree with the idea that they have the right just because they managed to get 500 karma on some webpage. That's technically easily done by just saying 'just the right thing' and getting all the updoots. At that point, it's really not worth much.
But thanks for explaining.
