Thomas and Andrew; I think both of you are right...Very often,persons who belong to any concrete ethnic or whatever group,need to join themselves,as a way of recognising each other,and sometimes,to help each other too.Because difference,or the fear to difference,to the unknown,has been the "battle horse" that other persons included in "normal parametres" have used to marginalise,depict when not simply destroy who have this other label of "different".Surely for an unconscious fear of being in their innest self just like these ones...This and the power wishes have always been what have create and developed wars;the rich against the poor,the powerful against the weak,the "normal" against the "different".Maybe is something inherent with human being,but it's time to change it,or at least trying to change it.And sometimes one must begin for the semantic,as the first step to be free of labels and of what they mean.
