Whether to treat shyness or not....

Vijay's comment to my post on shyness has added a new dimension to the discussion. Whether undesirable traits / behavior etc are to treated or not ? His observation about the attitudinal shift towards different sexual orientation is true. Psychiatrists had earlier labelled homosexual orientation as a disease . Now the society (though not fully) has become more tolerant towards this. Homosexuality is also thought to have a biological basis.
Unlike this issue, shyness is not a matter of choice. A homosexual person chooses or prefers this orientation; he enjoys this; only problem is the disapproval of the society. Whereas shy person does not choose to be shy. He is not enjoying this; he wants to get rid of this. This is more like a type of homosexuality which psychiatrists call ego dystonic homosexuality - a state that is not acceptable to himself. Homosexuality does not cause any impairment or distress other than the biological impossibility to bear a child. Even this problem may disappear in future, thanks to advances made in reproductive medicine. Currently treatment is offered only to ego dystonic homosexuality.
A shy or anxious person sees himself as deficient and handicapped, although in a lesser degree compared to many other handicaps. I agree to Vijay's point that we need to treat only those who want to get rid of their shyness.
