If a flat-Earther was sane, they wouldn't be a flat-Earther. The only decent option when dealing with people like that is to ignore them.

Well, at least you admit how closed minded you are and useless to discuss with ;P

Seriously, people with zealous certainty looking for argument/debate should be ignored. However, curious and earnest students interested in discussing alternative views and having their perspectives rationally criticized/challenged should not be ignored (even, and perhaps especially, when their views appear crazy!).

Sitting around always agreeing with one another is as anti-intellectual and boring as refusing to consider you could possibly be wrong!
