In the case of BDSM, individuals would perceive pain, torture and such in a completely different way than what society seems to view as "normal" for individuals; BDSM is viewed as an abnormality. What are the standards of classifying something as an abnormality?
BDSM has been explained under a medical and a psychoanalytic perspective. What if this is just another type of normal individuals? What if the case of BDSM - which seems to be the "exception to the rule" - is similar to the case of "homosexuality"? What if by exploring this case further we arrive to the conclusion that biology and psychoanalysis are not required since these individuals are simply different? Would that necessarily extend to a general reconsideration of the term "abnormality" or even the need to change people's attitude towards the term? Should the "stigma"; if this is inevitable, be given to all individuals that are "different" or only the ones that would possibly be dangerous to the rest?
