I would never make fun of conventional Islam. That's against just about everything I believe in.
By radical-Islam, I mean fundamentalism in general, something I attribute to cold seriousness and not much else. Islam is just the most prominent example of fundamentalism, so I mentioned it as well.
Islam is a beautiful and compelling religion and one that I think would set an example for other religions if not for the bad stereotypes running rampant in our media. I think that people who think being a Moslem is a bad thing (like those people who "accuse" Barack Obama of being one) are low and ignorant.
Regardless, I was a douche, and the implications I'd made were bad. I'm deleting my original post so no further misconception can be made.
To briefly go back to the Zeppelin thing, you should get this two-disk "Best of" appropriately named "The Best of Led Zeppelin". I got it for ten bucks new. Don't buy it on Amazon because it sells both CDs seperately, but if that's the only deal you find, and the one I got was a mutant or something, get the Latter Days disk, because it has both No Quarter and Kashmir on it.
