Good for the ACLU.
I grew up as an atheist. My parents didn't raise me to be an atheist, they just didn't raise me with any religious teaching at all, and by the time I heard about this God stuff it all sounded pretty silly. I had some teachers in school who tried to sneak in religion whenever they thought they could get away with it. Sneaky bastards, really. I mean, they obviously gave this stuff a lot of thought. It was important to them to try to get away with as many God and Jesus references they could. Not most teachers, of course, but a few.
Anyway, things like "God bless America" are not neutral. The evidence that they aren't neutral is that people like the teachers I referred to are constantly trying to get it into the classroom. If it was neutral they wouldn't give a shit.
