The statement that "social conservatism is a luxury is about as idiotic as anything I've seen on FreeRepublic -- for two reasons:
1. Almost every destructive economic policy in this country can be tied to a disastrous social policy that has no basis in Natural Law.
2. Political candidates who describe themselves as "economic conservatives and social liberals" usually end up being reliably liberal on economic issues anyway.
You're certainly free to ignore these points, but you do so at your own peril.
2. 90% of the time agree. Which is why government should stay out of social policy business.
