I wonder if down votes should be lightly nerfed. The idea would be to make it easier for people to post mildly unpopular opinions in hopes of furthering discussions and weakening brigading. I imagine there are a lot of people who comment once, get downvoted and then either never comment again, or only comment in ways that are safe and appeal to the community’s biases and sense of humor.
Something like requiring 10 downvotes to drop from 1 to 0.
Oh, it would also discourage spite downvoting since it would be hard for any one user to push a persons comment to 0.
