Don't you love the effort on FR lately to redefine conservatism so that Christians are excluded from the definition? I wonder what Washington, Madison and Lincoln would think about that? Actually, scratch that, I don't wonder at all, I'm pretty sure they'd think it was coo-coo for cocoa puffs.
The efforts of fundamental Christians to expand the powers of government by imposing legislative morality flies in the face of limited-government conservatism. I would be less suspicious of Christians if their entire agenda wasn't about turning my government into a theocracy. Now if you could set aside your social agenda, I would welcome your support of smaller government. If not, then maybe you and the other Fundies should go form your own party and stop trying to hijack ours.
BTW, Lincoln was not a conservative. He expanded and abused his authority, but he saved the Republic. He was a social liberal. He was a "Christian" but thoroughly rejected concepts like Hell and Original Sin and would probably be labeled a RINO by today's standards.
