Recently I came across a question with a couple of answers that I completely disagree with. I think only about the content of answers -- their form is perfectly OK. I just believe that answers are utterly wrong.
To make the thing worse, these aren't factual answer, but the kind that base on opinions / experience so I do assume that there isn't one universal answer for a problem. At the same time I can say that, basing on my experience and knowledge, I would go even that far to say that these answers are harmful. Yet still it is only an opinion, not a fact.
Now, should I downvote in such case?
