With atheist/agnostic liberals (read: most people I meet on the internet), who succumb to the bullshit of 'the rich hoarding all the money' and 'the temperature went up one-tenth of a degree. Ah!! We're all gonna burn!', I can tolerate because they at least are above the tricks and games of religion.
With Christian conservatives (read: my parents), I really love talking to because they openly rip on Barack Obama and every other crazy eco-dumbass; they say 'What they want is a utopia. They strive for this perfect fantasy world that can never exist.' And they're totally right. That connection I have with them becomes a little diluted though, when they then say, 'Yep; the only utopia is that with Jesus Christ in Heaven." That kind of pisses me off, but I can deal.
But liberal Christians... gawd. Make me want to absolutely pull my throat out of my ass. They come into Church, talking about how 'the professor at my school told me God isn't real. He's so whiny!' and then all the other people in the Church are like 'yeah, we should pray for him to let him experience the love of Christ.'
But then when I engage any of them in politics, they start spouting the ridiculous 'there's no guarantee the rich will spend their money' and 'social security gives stuff to people who could never have it otherwise' bullshit that they learned from the exact same professor.
