I'm totally with sfem on this. The concept of "a problem" is borne out of social conformity and the subsequent conditioning to believe anything that isn't deemed "normal" by society is a problem and therefore needs to be corrected.
All one has to do is take a look at Nature to realize diversity is not only the rule, it's vital for the survival of the species, human, plant, animal, insect, etc. The true "normal", as defined by everything that exists, is unique and that means different. That can be simply proven by the fact there are no two things on this earth (or anywhere else for that matter) that are identical.
Our "problem" is, was and has always been, a socially created one. When we leave it up to man to decide what in Nature is normal and what is not, we are in serious trouble.
