zen, im sorry but i gotta say, ur idea of no arguing/ stating an opinion about anothers opinion, is clearly liek a dictatorship, there is a reason ppl argue/ give their opinion to other ppl and have ppl criticize them and things liike that, it happens in everyday life, just about everyday in work im sure, and at home, there is no way u can possibly get rid of opinionating on opinions, it is human nature to put ppl down, or criticise, sry bud, but ur idea is unralistic
edit: and that reason stated above is to correct,prove a point, teach, learn, etc.
