I don't either, and I think you misunderstand my intent. I'll clarify. Christianity supplies the backbone of our nation's founding documents, the successful parts of our national identity and culture...in short, America used to be synonymous with Christianity, and in many ways still is.
However, USMC stated (and I quote), "Gays are just another sin," something that shows where the line between the religion that is Christianity, and the liberty - guarding government that is supposed to be this republic, exists. I'm just making the point that if you are a Christian, you won't be able to hold the government responsible for allowing people who are homosexual, for instance, to do the same things that non-homosexuals do. The price of liberty for all, as long as you aren't violating someone else's rights, is that people can do things without your approval.
This republic has been a noble experiment, but a break between the beliefs of traditional Christians and the more...ah..."liberal" elements of our society. Rome faced the same test...the test of whether a republic, or any nation, can persevere through evolving cultural norms (good or bad). We may survive this as a republic, but only if all the major parties can agree to respect their differences and leave one another's freedoms alone. Our freedom to have arms similar to the military as the Founders envisioned, their freedom to have guys marry guys (gag), etc.
I don't think we'll make it, though.
