I agree with the other answers, but this needs some response:
Should I report?
I'm assuming you are talking about raising flags, since this is the immediate way way have to "report" problems. If the dispute turns nasty you should certainly flag the comments that are rude or offensive.
However... you should not flag because you want a moderator to step in to decide who is right. Two reasons. First, it does not scale. Moderators are not experts in all areas of the site they moderate. Also, if they started doing this, they'd soon be doing only this, because determining correctness is not always quick and because a lot of people would pester moderators to step in. Second, if moderators stepped in to resolve issues of technical correctness, then what is the point of having a voting system?
