Um...
Buddhism is secular, that doesn't mean all atheists are Buddhists. Still, I wouldn't have a problem with it if someone called me a Buddhist, or said I'm not atheist, or if they called me a Christian. I know what I don't believe in. I'm well acquainted with me. Sorry to rob you of your big "gotcha".
It's not dangerous to say Christian groups have lobbied to have Christianity forced on public school children in America, because they don't make any business of hiding it. Unless, are you saying Christians are a danger to people who stand up for their human rights? Is this another argument for atheists to not bring up child molestation cover-ups? Also, I very specifically say Christianity is the religious group that I'm at odds with, because it's the only one that effects my daily life. For the last four hours my neighbor (the local postman) has been blasting country western Christian music. "You don't got love if you ain't got Jesus!" "Whatchu gone do when your time comes to repent? Hehe, yeehaw! Whatchu gone do then?" Nice, fun lyrics. You're right. I should never make the claim that it's fricking annoying.
This strange argument to try to convince atheist people that they are religious will in no way benefit you. Even if you somehow convinced us that we had some irrational belief system (I don't), it wouldn't elevate Christianity above criticism. Sorry. You are not superior to other humans for having faith.
