Jackie London & Emotional Guide Dog, I'm just going to post one response, because you're oth essentially making the same argument, so I'll just 'kill two birds' as the saying goes...
First, as Jackie London asks, what is religion? Religion includes culture, and practices, clothing, rituals, etc. However, that's really surface phenomena. Fundamentally, religion is, and is generally understood to be, belief in some particular faith. I'm aware many Jews are essentially atheists who cling to a culture, and traditions, that they value, I know a Rabbi who is like this, however, to put it bluntly, I would say they are not really Jewish. Of course, I'd be more diplomatic if I was speaking to them, personally, but that's it. Without the actual belief, it's just a tradition, or a style. What seperates religion is the beliefs. As the colloquialism goes; "Sticking feathers up your.."
Alright, now that's out of the way. Now, Emotional Guide Dog's assertion that I'm judging unfairly by disproportionately looking at the most egregious examples. Well, I'd have to say I think that's incorrect. First of all, the big offenders are the Abrahamic faiths; Judaism, Islam, and Christianity. Collectively, these faiths not only make up niine-tenths of the religious landscape, but of the population of earth. That's not cherry picking. Moreover, beyond all the horrible things religions do, and, admittedly, some, like Tibetan Buddhism, are less destructive than others, they ALL are alike in one respect; they are fundamentally illogical, and antithetical to logical thought. This ALONE is reason enough to oppose religion, beyond all the horrible things we do. To paraphrase Sam Harris, besides killing eachother, the only way of communicating and resolving our differences is conversation, and religion is a conversation stopper. Religion takes people out of the game of reasoned discussion.
Just as a sidenote to Jackie London, I'm aware of the hysterical, and racist Islamophobia that has become disturbingly prevalent in the United States, it repulses me as well. The US media tends to reinforce this attitudes which is one of the millions of reasons why I prefer independent or foreign media.
I'm not picking on Islam.
Now... The one thing that I will concede, just so that I'm being clear, is that I understand perfectly that there are billions of religious people out there, and most of them are largely decent people. The most violent and bigoted individuals are not necessarily representative of the rank and file. However, they are absolutely representative of their respective faiths. What does the Bible say about women's rights or homosexuality? Or the Koran? Read the books, it's all in there. These books contain very obvious, and explicit exhortations to violence. According to the scripture homosexuality is an 'abomination' that should be punishible by death. That's not subtle, there's no room for misinterpretation. Read Levicticus, whatever, just pick a page and start reading, in no time you'll find impetus for some atrocity or another. The Osama bin Laden's and the abortion clinic bombers read the books cover to cover, I assure you. They can quote chapter and verse. They were able to square everything that they did with what they found in those books, in fact, that's where they got the idea. There's definitely a problem within Islam, but I'm not singling them out by any means. For Christians to decry Islam as violent and brutal is the definition of hypocrisy. Devout christians massacred, and tortured heretics, really, in thost abominable ways you can imagine, just about the worst acts of sadism you can conjure, for centuries. As I've said, the individuals doing this read the book cover to cover. They read the sermon on the mount and they were able to square their actions perfectly with that book. The new testament does not repudiate all the awful shit in the first half, even jesus has his bad days where he says things like if you find a heretic you should "bring him hither and slay him before me." It's pretty easy to see where people might go with that. So I'm not pre-judging, I'm judging. These books are filled with bigotry, sexism, intolerance, and deliberate, open exhortations to do violence.
Now, I don't deny religions do some very good things. However, I would say that religion doesn't offer anything real that couldn't be acquired, or would be better off being acquired elsewhere. The catholic church does a lot for charity, however, it also instructs people who have no other source of information, in the most AIDS-ravaged parts of Africa, that they shouldn't use condoms. I fully support charity, humility, graciousness, morality, etc., but none of these traits are inherently religious. None of these traits automatically follow from blind certitude in a magical creator. Whereas the belief that all homosexuals should be killed, that women are essentially chattel, and all heretics will burn in hell forever absolutely come from those respective texts.
Religion, moreso than anything else, is proclaimed to be beyond the scope of conversation. Unlike sports, science, art, politics, and everything else we have to give religion a wide berth. We can't discuss it, we can't question it, and we certainly can't criticize it. We need new rules of conversation. We need to break down these barriers and have the guts to call a spade a spade. I'm not being hyperbolic when I say religion is the opposite of civilization, that's an absolute fact. If we want to build a better world, if we want to get it together as a species, we must fianally shrug off these pre-medieval dogmatisms. To quote Sam Harris; "There is no possible future in which aspiring martyrs will make good neighbors."
