Uh. three issues:
1. "Under God" was not part of the original pledge of allegiance. It was added during the Cold War.
The other change to the pledge of allegiance happened in the early forties. The original pledge of allegiance was done with outstretched right hands -- non e of this hand-over-heart stuff.
2. Is the United States "Under God"? Do we obey God? Do we all recognize God? Can we actually confess that our state is obedient to God? which one? whose religion determines that? I'm sorry, a facile "it's the same God...." won't cut it. Why the hell do you think we have so many different denominations in this country? It's in part a dispute over the nature of God. Now, we're supposed to confess that we believe and follow a God when our legislators and president don't go to the same church, and have very different notions of what God is.
3. I'm sorry. No pledge of allegiance that's forced upon schoolchildren, including foreign nationals, is worth a damn. Now add that it's allegiance to a flag and not a country, and it's even worse.
Frankly, I consider the conduct of the senate shameful. 99 people and not one with a pair of spiritual testicles to stand up for what's right? Now that's the kind of stuff that makes me worried about my country.
