The problem is that the demands of conservatives are out of control. They utterly reject the power of the mind to reason to a plausible understanding of moral values and their application to complex circumstances. Conservatives only use reason to extend by remorseless logic the demands of their primal moral feelings. They do not see that their views, when pushed to their logical limits, are incoherent.
The Newtown murders are a perfect demonstration of that incoherence.
