Again, I agree, but only in context. On Hacker News, I totally agree that downvoting debatable views that are expressed poorly is totally unnecessary. If it isn't a statement that is outright dangerous or intentionally hurtful, my bar for downvoting here is very high. I would trust the audience to discern for themselves. On Stack overflow, you are essentially there to teach people something. "Don't ever do X" is not going to teach something. Unpopular ideas (and even some popular ones) should be backed up with cogent reasoning, and I think downvoting (with an explanation) is the best way to tell future visitors "this is (probably) not the answer you are looking for".
