If you don't think that religion is affecting you consider the following:
If you think overpopulation is an issue, why does a major religion prohibit condoms and other forms of birth control
If you think that you should be able to marry whomever you want, consider the controversy on gay marriage
If you think that the creation myth is not science then why are state legislatures and state school boards still considering rules to teach it alongside evolution to our youth
If you think that women are equal to men, why are hundreds of million of women not afforded equal rights in Muslim countries
If you think that freedom of speech is important why was EVERY major news outlet in this country afraid to publish a cartoon of Mohammed
If you worry that the conflict between Israel and the rest of the ME will spark a nuclear war then consider the role of religion there
If you or a loved one is faced with certain illnesses and you are looking for a cure think about why stem cell research is constrained here in the US
If you lost a loved one in 9/11 consider religion's role in that
If you think that the sexual abuse and the cover up this abuse and the protection of the abusers is wrong, why hasn't the government come down on the catholic church like it does lone offenders like at PSU?
If you think that the mutilation of females in the form of female circumcision is wrong why is this practice allowed to continue (the whole concept of male circumcision is highly questionable as well but less harmful)
If you value free thought why do we allow children to be brainwashed and indoctrinated into fundamentalist religions before their critical thinking skills are mature
I could go on but I think you get the point.
If you want to practice witch craft and be completely ignorant on your own time, I find it sad but I'll let you do it. As soon as your wacky beliefs impact my world I do get aggressive about it PK because it is based on made up fairy tales. We don't pass laws based on Santa's naughty and nice list and we shouldn't pass laws based on the psychotic visions of an illiterate shepherd who had visions in a cave, a shepherd who spoke with burning bush or some "man" who strangely couldn't have a Y chromosome that had zombie powers.
A few things come to mind. Religion helped bring down Communism and played an important role in the abolition of slavery.
Also, this idea that we'll someone live in a more moral or peaceful world if there wasn't any religion has been proven wrong. Atheism was/is official state doctrine in the Soviet Union, North Korea, China and Cuba. These countries have murdered/starved to death uncounted millions in a short period of time. Moreover, I would submit that this was a product of atheism. Leaders of at least two of these countries, Stalin and Mao, were completely nihlistic and hence didn't give a thought to widespread death in their own countries, which was in large part influenced by their atheism.
This isn't to say that atheists are inherently immoral. By the same token though, religious people, and in fact most religious people aren't intolerant and backward as your post implies. The parade of horribles you present, are mainly the result of backward cultures that would most likely exist whether the actors were religious or not. For example, there are virtually no Muslims that have lived and grown up in the US engaging in acts of terrorism or even expressing any support for it. That's because, even the religious ones, they wanted to escape the more backward aspects of the culture of their homeland.
Look, I'm not religious myself, and am actually more or less atheist. It's just completely naive and simplistic to think that we'll live in a more advanced and less cruel civilization without religion.
