Good point. Here in Arizona, our attempt to amend the state constitution to ban gay marriage failed, most probably because it over-reached and proposed outlawing any legally-recognized gay relationship. Many conservatives support civil unions, as long as it's not "marriage", because many believe a committed, monogamous relationship is better than none, especially for those involved in a lifestyle fairly devoid of "traditional" values.
To me limited government does not only refer to the size of government but also its reach. Like my father, I think the social conservatives are reaching too far, damaging both the body politic and the body religious, but not intentionally. Perhaps I and my father are wrong, but what if we are right? Serious questions for sure. I'm series. ;-)
