Conformity is valued in all groups. But in some non conformity is punished in worse ways. Growing up in Anglo American society one gets used the idea of individuality being tolerated and sometimes even respected (if one can prove his merit). (It was considered an ideal to aspire to to be your own self in the 1960's) But in many groups individuality is harshly punished. Sometimes because the group is just a small religious group there is not much they can do legally. But still they tend to label anyone that deviates from the norms as a kook; and because of the power of the super-organism, this label can in fact stick. This problem is impassible for all human beings.
For being part a of a group is no different than a cell that is part of a human body. Though it seems self sufficient. Taken away from the larger body it decays and dies. So again if one does not want this to happen to him or her he should be careful what kind of group he joins.
At any rate I am pretty sure that the fact that being part of a social organism is so essential to the human being that this must be the reason Habermas [who some people consider the greatest philosopher of this generation] is not as against Marxist theory as most serious philosophers are. He must see it as a kind of social paste.--and who knows maybe it is. But my complain is that once a long time ago the Constitution of the USA was a marvelous social glue. But the effect of the socialist policies introduced in the 1960's did what socialist entitlement policies generally do--they create interest groups who have no sense of identity with the general society, and instead try to suck the life out of the larger society. This has happened in America.
