People who don't want God mentioned in public school are also free to send their kids to private schools or homeschool. Why is it that only the believers are told to take it or leave it like they are some kind of second class citizens? While the US has no offical religion, Christianity in it's various forms is practised virtually everywhere in this country. Since the majority of the citizenship is Christian there should be no problem if the schools reflect that in the public school system. If atheists don't like it, they are free to go elsewhere and stop forcing THEIR belief system on others. Lack of belief in God or a god is not the neutral position that many would have us believe.
And people wonder why Jews tend to vote liberal and Democratic.
Schools reflect the fact that the United States has, since the time of the great General Washington, been a secular country. Besides which, I pay taxes too and have no desire to see public schools turned into Evangelical cultural preserves.
