This is a really cynical view of conservatism and I have a hard time seeing how you don't see half the country as evil if that's what you think.
Another view might be: this stuff is so complicated, and as you pointed out it's so difficult for political leaders to have real empathy for people in these situations, there is a high degree of chance we will screw this up and make it worse while trying to help. Example: homosexuality being in the DSM. Or really much of the history of how state institutions have treated the mentally ill, which has mostly had to do with keeping them away from the non mentally ill and not actually treating them.
