Is conservatism curable?

In a brilliant article, Steven Jonas, Professor of Preventive Medicine at the School of Medicine, Stony Brook University (NY) Is Homophobia Curable?.  Don’t misread that. He’s asking is homoPHOBIA curable.

This suggests another question: is conservatism curable?  For conservativism is clearly a moral disease of character, leading people to think it’s OK to: enrich the rich at the expense of the poor and the middle class; torture;  start immoral, disastrous wars; shred the Constitution; intentionally bankrupt the US Treasury as an excuse for destroying social programs;   privatize government programs as an excuse for handing billions of dollars to friendly corporations; steal elections; suppress scientific evidence; exploit bigotry and fear for political advantage; and so on.
