X has a point.
I've often said that although racism will eventually eliminate itself (via several thousand years from now cross-breeding resulting in all of us being one muddy light brown - this is, of course, if we make it that long) prejudice will exist forever, because it's an inherent part of humanity. We will always find things with which to divide ourselves and fight over, and to that extent, outlawing religion will not eliminate war.
However... (carefully stepping over fence)
To utilize a Satori quote I've read enough times I don't need to find, copy and paste, "religion is a political tool", and it certainly makes a whole bunch of shit a lot easier to manipulate. Although it could never eliminate war or sex crimes (another George Carlin quote: "you could outlaw religion and a lot of these sex crimes would go away in a few generations... but we don't have time for rational solutions!") it would certainly reduce the presence thereof and make it much more difficult for people to be manipulated into thinking that killing a bunch of people (be it via swords and crucifix-adorned shields, inquisitions, witch burnings, or 767's) would be a good idea.
Overall, I think it's a good step forward, although not the ultimate solution to all the world's problems. Unfortunately, it's pretty much impossible. We have to hope we evolve beyind it...
