Draugnar, you make a false equivalence.
Saying that the government has no business teaching religion, but that to teach secular ideas (you know, math, science, etc) are the same as teaching religion is insane.
My position, as one of webdips "militant" atheists is that the public schools and public institutions in this country have no business having anything to say about any religion, pro or con.
Also, you saying "Hell exists" has precisely the same amount of truth if I asserted that Russel's Teapot existed.
And yeah, you can reel off quote after quote from your book that says women are subordinate to men, etc.
And the fact that you in the modern age can explain that away (and that your antecedents would disagree with your interpretation) is what scares me about religion.
It can be reinterpreted and redefined to back up basically any position you want to take. It has no actual meaning itself, but is used as a piss-poor justification for what you already feel or have been indoctrinated by others to feel.
I'm sure you could find justification for anything ranging from curtailing the rights of non Christians. Or the forcible conversion to your particular flavor. Or the execution of heathens and heretics by immolation.
All of these things have been done, and their interpretation is just as valid as yours.
So basically, when I hear people use the Bible as justification for any act, I really hear "I can't think for myself, so I need a two thousand year old book, and you better hope that I'm not going to do anything really terrible as a result"
