i think its more societies fault than nething else.
you say you have been called goth because you like to wear black... im asuming these people dont know you right? so ... can you blame them? black clothes is how mass media portray "goths", on tv shows, on music videos, on the internet... people start automatically associating black with being "gothic". generally this is how all western stereotypes are created, and is not so much about segregation or discrimination, but rather the way our society puts labels (at times unintentional) on certain groups of people.
