The court is correct, the pledge as written in unconstitutional, and has been ever since it was written in 1954 to help indoctrinate the kiddies against "those godless commies."
Just because you like the pledge, doesn't make them any less correct.
Just because your faith is important to you, doesn't make them any less correct.
The Fed gummint is specifically forbidden from establishing any kind of religion, or from preventing the free exercise of any religion. THIS IS A VERY GOOD THING AND MUST BE PRESERVED. Otherwise we'll have Northern Ireland on our hands, or the kind of crap that goes on in the Middle East, on our doorstep.
As long as schools get their funding from the gummint -- which is also a SUPER BAD IDEA -- then they must not include religious instruction or indoctrination of any kind. Period. End of story. Deal with it.
If you want your kids to say "under God," send them to a totally private school, where it's just dandy. In fact, I think that's a good solution to the whole problem: eliminate public schools. We did perfectly fine without them for a hundred years, and they've done nothing but screw kids up since they were started.
