Downvoting in general is a pretty poor tool. What exactly would be lost if you could not downvote? Upvote or flag it if it's blatantly wrong; better yet, respond with the correct info. The main problem with down and up voting is that it's "apparent" which results in people just doing it to further support an already up/downvoted item. This results in not actually attempting to understand, imo.
