I've seen a lot of questions on here that ask something like, why is blank important because the way I see it... and then they go on to list a string of facts that aren't true, and there question has a lot of down-votes. Should we DV people just because their ill-educated in one part of music? Isn't the reason they're here to learn, to grow from their mistakes? Why are we down-voting people just because they haven't learned everything about music yet? I know I've asked a few questions like this, but it didn't get down-voted...
If there are "facts" that are the basis for the question itself, then perhaps the question makes no sense if those assumptions are actually false. I could see those attracting downvotes. A much better approach, though, is to leave a comment explaining the mistake and asking for the question to be edited and improved.
That said, without some examples, it's very tricky to know what you mean - your assumption that people are down voting because of this is not necessarily true. Unless the downvoter commented that that was the reason, then you are just guessing.
