It's kinda interesting that this subject is coming up again after all these years. Something very related (not nessicarily similiar) happened in 1943 in the Supreme Court. Before that the supreme court ruled in the Gobitis case that all students must say the pledge. Then in 1943 in West Virginia State Board of Education v. Barnette they rule that student don't have to say it, if it violates there own personal convictions. Interesting enough if I remember the case is that it was brought up by a Jehovah's Witnesses who felt it was against his religion to salute it or say the pledge. The part of the bible concerning "bowing down to graven images". In relation to this, an easy application of this law is all thats really need to settle the problem.
Technically the guy is right in that it is an endorsement of the Judeo/Christian God. But Christian offshoots were that was around when the country was forming. The Puritians came over to america because they had lost power and the others wanted them out of the country because they couldn't put up with the puritians amazing strick laws. The rest just came over in search of fortune mainly, what greater motivation for the human race, right?
So personally I'm against it. People seem to have ants in their pants about so many things today. Considering the voucher ruling just came in, if this cases makes it too the Supreme Court then we aren't really sure how it will end up.
