There are five kinds of wisdom: the first in fact is a desire, so when people say that marijuana should be legalized it is not an opinion rather desire (most of gay rights; obviously certainly hate; i.e antisemitism, black or white radicals, terrorism based on Islamic fascist ideology – for in their faith they are meant to dominate etc.) The second is inherited – we all inherent (often subconsciously) the opinions of those who came before us (so for example, democracy makes sense to an American, while Islam which puts Allah as defined by Mohamed (who being insane, thus there needs to be an interpretation, hence as defined by whichever imam, as defined by whoever he learned from ,hence Wahhabisim, sunni, shia etc.; which we find the same notion in the over 30,000! brands of Christianity etc. etc.) Then there are those precious souls who break out of the stupidity of the past to discover truth (Abraham was one – but many today being disillusioned with the notions of the past are doing this – quite naturally this leads one to God, but compare not those who inherited the dogmas of the past to those who DISCoVER for they are diametrically different, one is without, the other with, intelligence)
