Assuming you're not harming anyone else, live as you see fit. I believe that if by living and learning you happen to ignore religious "law" god will understand it's all a part of growing up. If god does will not understand then he is not god, so why worry about it?
If god was so offended that creationism is not taught, why didn't god write/inspire his holy book/s correctly the first time?
Don't get me wrong, I completely agree creationism must be taught alongside of science, my problem is
which version of creationism to teach.
Once we can decide which religion is true and which is false we can finally begin the holy work of teaching the right version of creationism and all that good stuff.
Of course I'd not want to put many different people of different religions in a room to debate this, god might be offended by their consequent behavior.
Come to think about it, if god is so bothered about people believing in him and their eternal souls and all that, why doesn't he just say so? heck Amazon will give him an exclusive on the Kindle Fire HD. I can see it now "Kindle Sin Hellfire - GOD EDITION!"
