if a topic seems to have two valid opposing sides, it probably means you don't understand it well enough to tell which is correct

Or that perhaps those sides are extremists while some optimal balance between the positions is required. E.g. "vitamin supplements are useless and evil" and "you will probably die unless you have some" are both unlikely to be "correct".

(OTOH, perhaps you meant "which is correct" in a sense that includes other possibilities besides the two opposing ones, in which case, never mind, carry on. ;-) )
