One only has to have an opinion on something these days to get hammered by people who profess to know everything about the subject. The problem is people get polarized into groups, and the point of the discussion is lost to endless bickering about who is right, and who is wrong, when neither side has the complete picture, or the entire facts.

I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Isaac Newton, From Brewster, Memoirs of Newton (1855)
