For me it's not a question of whether a party is "perfect" or not, it's a matter of, does a party's platform clash with Biblical authority? I have to be a Christian first and foremost, above all. I can't play political games with my soul.
A perfect example of Rats alienating Christians is a poll I saw whilst trolling over at DU earlier today.
The question was: "Should the phrase 'In God We Trust' be taken off US currency?"
They voted 10 to 1 "Yes."
I imagine the result would be the reverse here, if not unanimous "No."
