Absolutely. I've always been amazed at the number of people, here on a conservative forum, that are shacked-up.
As I mentioned in an earlier post, "shacked-up" needs to be defined a bit closer. If you're talking about meeting someone and immediately moving into their place, then I agree. If you're talking about moving together after engagement, I think that's a different story.
Incidentally, there's more to conservatism than the social aspect. Many folks here are primarily fiscal conservatives...
I'm always shocked at the number of people who think they are conservatives,and that it has anything to do with sex or other lifestyle issues. It is a political stance that has to do with limiting the power of government and maximizing the freedom of the individual citizen.
