Religion is dangerous and it shouldn't be teached to children. I doubt most sane adults would actually believe in religion if they came in to contact with it after the age of 16 or 18 while they had some basic scientific education in their childhood, like physics, biology and some math. As long as someone is a rational person who's at least somewhat proficient with the scientific method knowing about our limited capabilities he has at least to acknoledge the fact that all religions, even buddhism are build on assumptions. That for it self isn't a big issue, as even scientific research is build on faith, faith in your hypothesis or the correct measurment, but what you have with science at the end of every process, the proof, is something that's completely missing in any religion or spiritual belief. And by teaching children fairy tales as truth, we're simply put indoctrinating a large number of people to believe that this is a reality without any real evidene to back it up, outside of 'I feel that it's the truth!'. By making someone believe that it's possible some guy who was wandering trough the desert 2000 years ago, walked over water or turned it in to wine, is no different from convincing people that dragons, cobolds, unicorns or magic to be true and real existing things.
