Albinism and other human differences have been used as metaphor for hundreds of years. Authors often give their characters physical differences as signals to let the audience and other characters know that the effected person is inherently evil or not to be trusted. Shakespeare gave King Richard III a hunchback for this reason.
Although sometimes our “condition” is used to poke fun at us or used simply for shock value, many times it is used to convey a deeper message.
