You can't expect everyone to be as solitary as you wish to you, nor can't you expect everyone to know themselves. We are a species that evolved through cooperation and continues to need to cooperate with each other.

Our whole culture is based on hegemonic power structures. We are way too far from establishing something else in our ways of thinking and in our culture (if that is even possible). What we currently can do is to question the hegemonic opinion more often than before.

Advertisements do work on most people, since they are constructed to work on most people (our knowledge on psychology is scary!). Lucky you, that you are beyond consumerism. But think of the children and how many are taught to "not be consumers"

It is a shame that some people think that the "need to fit in" is the root of evil here. The contrarian position of the "need to be solitary" can be just as evil. Both needs are not evil themselves. It depends on how they are used and in what harmony they are used together. I am certain that we need this need to fit, so that humankind has an inclination of cooperation instead of an inclination of isolation. A general tendency towards trust to others is what made humankind humankind. Never forget that.
