I'm talking about all religions and every religion in general. What are your reasons?
Religion and religious persons impose their faith into public policy and politics. Where it clearly doesn't belong.
Religion is still very much mediatory in the schools of nations such as Republic of Ireland, where it has no place. Churches were built for a reason. This makes many members of other faiths and no faiths feel uncomfortable and excluded during a time when young persons find it difficult to fit in as it is. It isn't a matter of talking about religion, but actively telling young persons to practice it mandatory.
Many nations make it difficult for the non-religous to have any sort of successful career in politics (and being honest about their lack of faith at the same time)
Many religious groups impose their views of abortion on others and seek to make abortion illegal. Because of religion in other nations it now is or has been for sometime, outlawed medial practice. Abortion is not murder, murder is the illegal killing of a human being, not a pre-human being.
Religion demonises many educational fields in contrast with its doctrine, such as certain aspects of history and many accepted theories
There have been cases in the United States and some other country where person's have lost their jobs due to lack of faith or alternative faiths and sometimes on the bases of sexual orientation (which is thought to be justified because of certain beliefs)
Religion tries to justify many forms of discrimination including but not limited to, homophobia, sexism, racism and class
Certain nations such as Iran and Uganda take their discrimination justified by religious beliefs a step further by improving atheists and murdering homosexuals
Religion has caused many to rebel against its corruption. While this mostly occurs in changing religions or declaring oneself atheist; that is not always the next direction for some. For some they take that faith and change it for their own purposes, often resulting in more extreme and harmful faith systems mostly regarded as cults. These cults involve all sorts of dangerous acts, such as mass suicide and sometimes violent attacks of non-beleivers of their faith.
Religion has literally caused people to go to war due to the influence of the faith and disagreement with certain policies based on religious beliefs (especially when a doctrine influences such actions)
is that a horny toad?
Omg I love that. Lol awesome
As Sam Harris puts it, religion allows people to believe their actions are moral, when in fact they are gravely immoral. To me, this is #1.
Science does not claim to have the ultimate truth. When new evidence is found, existing theories are modified or even discarded to accommodate the evidence. Far from being a flaw, it is a virtue.
There is no such thing as a complete theory. By their very nature, theories contain the seeds of their own destruction. In fact if a theory cannot be falsified, it is no theory, but just idle speculation.
For you to somehow think this is a refutation of science and that "eternal truth" is a justification for religion just shows that you do not really understand science.
In keeping with Val's comment, here's an article a bit too long to reprint here: http://wonkette.com/509246/sundays-with-the-christianists-home-scho...
Also, in keeping with Kai Jones' regurgitated platitudes, I suggest all interested visit a Christian blogsite, whose authoress claims to respond to every comment. In it, she thanks what she terms, "the New Atheists" for posing such intriguing questions, that Christians have been forced to think, in order to respond. I commented that if these "New Christians" had begun to actually think, rather than blindly follow, like sheep, then the end of Christianity can't be far away.
"Insanity is believing your hallucinations are real. Religion is believing that other peoples' hallucinations are real."

"One of the saddest lessons of history is this: If we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We're no longer interested in finding out the truth. The bamboozle has captured us. it is simply too painful to acknowledge - even to ourselves - that we've been so credulous. “

"Theology is never any help; it is searching in a dark cellar at midnight for a black cat that isn't there. Theologians can persuade themselves of anything."
-- Robert A. Heinlein --
I would say to Robert A. Heinlein, then, that he doesn't understand what theology and theologians are. Theology has a significant importance of understanding culture in both ancient, modern and post modern societies. In a sense it is a part of anthropology and encompasses all that is a part of the human experience - art, literature, science and the advancement and development thereof. Oh, and you don't have to be a theist to be a theologian: case in point, Bart D. Ehrman.
RE: "Theology has a significant importance of understanding culture in both ancient, modern and post modern societies."
Perhaps Barry, you have less faith in our Fellow Man than I do - had religion never existed, I have every reason to believe our culture would have easily been as rich, but different. The Masters might have painted galaxies and Super Novae, instead of angels climbing ladders to heaven.
