I hope you noted I specified "big-government" and put conservative in quotes.
My problem isn't with social conservatives, per se, but with those who want to impose on others via government. You're right...it seems many so-called Christians have never read Matthew 10:14. Their first response is to call for Caesar to impose their will on others.
And yes...
A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.
There are too many intoxicated activists.
Agree. And I did note your specifics about big government conservatism.
Obviously, people can be both small government conservatives AND social conservatives who practice a serious Christian faith. I see all too often an attempt to slice us in two saying that no one can be both, and that's just factually untrue.
But the problem, as you have said, is when less than fully educated, albeit mostly well meaning Christians force a very unconservative style of big government control on others, and entirely remove the concept of freedom from the equation.
I believe strongly that without morality, Constitutional democracy isn't possible, and that, I believe is where our efforts need to lie....... in returning America to a kind of integrity that was presumed in our culture before the left deliberately destroyed that integrity.
(Charles Colson has a very powerful series on returning ethics to our culture without forcing a specific kind of religion on anyone, simply called "Doing the Right Thing." I recommend it).
