The irrationality of disgust suggests it is unreliable as a source of moral insight. There may be good arguments against gay marriage, partial-birth abortions and human cloning, but the fact that some people find such acts to be disgusting should carry no weight.

I'm not for gay marriage, but I'm not for discriminating against people.

Human cloning is coming.

Southerners focus on the social hot-button issues, like abortion and gay marriage. But Indiana, like Iowa or Wisconsin or Ohio, is more interested in the traditional Republican issues - balancing the budget, integrity in government. It's a much more humble kind of state.

I've been opposed to human cloning from the very beginning.

I would not want to see any relaxation of the law prohibiting human cloning.
