This is a bad point of view and is what is leading to the degradation of HN as a place for people who see the world through a different lens. We have already lost a lot of beautiful minds due to heard voting. Downvoating is for items that do not belong on HN, nothing more nothing less. If you downvote because you do not agree with an idea you are actively suppressing discussion, no matter how strongly you disagree. Many time from people more brilliant that ourselves.
