Politics has absolute zero to do with religion. That false association was trotted in by the Jerry Falwell opportunists selling snake oil in yet another power quest.
If we were a theocracy, it would be relevant.
But we're not.
PERIOD.
As an anti-Godist, I know you hate that people vote their spiritual and religious values. They always have and always will: period. Tough to be you.
"Hate" doesn't even enter into it. It's a simple matter of definition.
Does politics involve, say, instruments of public welfare? Yes it does.
Does it involve the religion of an individual politician? No it does not.
Does it involve the officially sanctioned religion of the State? Only in a theocracy.
Something is either related to politics, or it is not. Religion is one of the latter. It's only the opportunist Fallwellian huckster types that would pollute the public discourse with such lame and self-serving false association.
I don't know what, say, Ted Cruz' religion is, or if he has one. And I don't need to. It's none of my damn business.
