"My last vestige of "hands off religion" respect disappeared in the smoke and choking dust of September 11th 2001, followed by the "National Day of Prayer," when prelates and pastors did their tremulous Martin Luther King impersonations and urged people of mutually incompatible faiths to hold hands, united in homage to the very force that caused the problem in the first place."
Sometimes, even an atheist can hit the nail on the head - incompatible faiths! The religions of the world make incompatible claims. Christians claim Jesus rose from the dead; Jews disagree. These are major differences, not minor. While it is theoretically possible that no religions have the truth, it cannot be that all are true. Gathering people together of different religions for prayer to their different gods is just an act of covering all the bases -- "we don't know which god is the true one, so we'll just pray to them all". Somehow, I doubt the true God - especially if He has gone to a lot of trouble to make men aware of Himself - is going to take that very seriously!
The only religions that could get together and pray in unity are Christianity and Judaism for they, at least, share the same God even if (to the Christian) the Jew only knows him partially.
One of the underlying problems of 9/11 was a religion, Islam, that condones, and obviously to some requires, killing of infidels - just look at the recent problem of the convert to Christianity in Afghanistan. Some will say that extremists have hijacked a peaceful religion, then I will say the burden is on the leaders of peaceful Islam to aggressively help put an end to those who have hijacked their religion. Other than some verbiage here and there, I have not really seen any such organized attempt.
Although there were old testament times when the God of the Christian and the Jew instructed the Jews to wipe out entire races, these instances were very specific in their rationale and were only for a very specific time and place. There is no generalized condoning of killing infidels in Christianity/Judaism - in fact, just the opposite is true. The Jews were commissioned by God to be a blessing to the nations. Roman 2:4 (NASB) gives the true definition of tolerance for the unrighteous: "Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing that the kindness of God leads you to repentance?" Christianity makes converts through persuasion and the opening of hearts - not by sword or suicide bomb.
If you were to gather religions together, then gather them in commitment to the preciousness of human life - committed to action not just words. Unfortunately, abortion-full America, would show up with bloody hands.
