Religion in Schools: Deflate the Argument

Seeing as I'm a 26 year old without kids, I really don't have too much say or the need for an opinion on this subject. As such my only opinion on this is about equality in any decision made on this subject. So I will keep it simple. The best reason for no religion in schools is the fact that not everyone beleives in the same religion. How can they teach Christianity in a public school if their religion is Confucianism, Hinduism, Islam, Jainism, Judaism, Shinto, Sikhism, Taoism or even Atheists? The only way that religion could be taught in schools in a non-biased way would be to teach all of the worlds religions. That definitely is not likely to happen in this life or the next. Let's say I'm wrong and we find a way to jam ALL the world religions into schools (as unlikely as it is). How do we teach this subject matter in a non-biased way. Everyone has an opinion and that includes the educators. I will give the "pro-religion" one argument on their side. Parents definitely need to talk to their kids about religion and the difference between them but this is another unlikely scenario and it still requires the one thing that the "pro-religion" will never allow: other religions taught. This is why we cannot teach religion in schools.
