The Kingdom Of God: How does that fit in?

In the gospel of John, we see the evangelist uses of dualailty quite often with light and dark, good and evil, etc etc etc. You get the idea.

But have we taken this dualism too far?

Is the kingdom of God a left or a right?
is the kingdom of God liberal or conservative?
is the kingdom of God modern or postmodern?
Is the kingdom of God emerging or not emerging?
Is the kingdom of God catholic or protestant? MB or Baptist?

I was talking with this sunday school lady the other day at Dan's church, and Wing and I started to debate the whole issue of the Kingdom of God and her answer was," The Kingdom of God is the love of God in the hearts of men."

I have many more thoughts, but I'll just leave it here and let the discussion begin.
