For me downvoting should be for at least one: 1 - Not relevant to the discussion 2 - Rude/Offensive/Prejudice, etc Downvoting means the comment get less visibility. In real life conversations, when you don't agree, you don't turn down someone's voice so nobody can hear them. You either reply saying that you don't agree, or you get them out of the discussion if they are 1 or 2 above. If any opinion that is different than the prevailing opinion get downvoted - thus, less visible - people are not going to see the different angles of the discussion. Even if it's an opinion based on wrong assumptions/facts, other people might benefit from seeing the correction on the replies
