Actually: I think racist people have a disorder, too. A paranoid delusion disorder mixed with irrelevant and ungrounded fears, leading to a skewed narcissism complex. Maybe put agoraphobia in there, as well. Racist people are nót sane.
In some sense, I do also think 'transsexualism' is a disorder. Let's face it; it's not a majority thing, it's self-destructive in nature, and for some odd reason, the mind/brains malconnects on the grounds of body-image, self-perception and suchwhat.
Good thing there's actually a partial cure for it, though. It's nearly completely curable. Saying it isn't a mental illness or disorder would result in no more help from psychologists, health professionals and surgeons.
In other words: I think it fits the bill.
