You said that you had never seen damage caused by religion which non-religion couldn't do as well. I showed an instance where you were wrong. To believe in the supernatural is decidedly religious and the root of a major disagreement I have with religion, the other issue being traditionalism and dogma. Really, when I speak about religion I am referring to both of those aspects.
There are things that are ultimately specific to religion, but like I said, there are other things are specific to other beliefs (for example, racism).
As strange as it may seem, you don't need religion to have faith. Look at conspiracy theorists. They have no reason to think their conspiracy is right except their own faith in it (and their craziness, but that's beside the point). If we're defining faith as having belief in something with no real reason, then you can toss in all sorts of things in there.
It isn't strange at all and as I already said, it exists for many things apart from religion. However it is within religion and other supernatural views that the strongest opposition to objective truth comes from. In religion Faith is idolized to the point where people think they don't need an answer to questions posed towards their beliefs and that simply calling it their belief is an acceptable reason to stomp on the freedom of homosexuals, prevent stemcell research which could help millions, oppose the spread of condoms in Africa, and stone women to death for adultery.
It is the particular religious ideas that become dangerous when the principle of Faith is applied.
Okay, I think I know what you're getting at now. The only reason that faith is largest in religion is because it's practically the only thing that contains it. But the people that are against homosexuality and such only believe in that stuff because of indoctrinated religion (which I'm against), not religion itself. Without indoctrinated religion, most probably wouldn't hate those things. Even without religion at all, the rest of them would probably still find a reason to hate those things.
And Conspiracy Theories are a bit different than Faith, since that creeps into the territory of being insane and unable to properly evaluate evidence because of emotional reasons. Even the worst conspiracy theorists I've seen haven't denied discussion about a topic simply because it's their way of seeing things, rather they are more interested in convincing others to their point of view, and will engage in debate about the truth. Theirs is a more common stubborn nature than the elevated fall-back position that supernaturalists/pseudo-science advocates hide behind whenever Objective Truth is trumping their claims.
I can give you that conspiracy theorists are crazy, but they are only an example. Faith is really something specific to religion, if we're defining it that way. Conspiracy theorists find "proof", religious people find faith. There's the occasional person that claims to have proof of whatever religion, but it's ultimately unprovable to anyone other than that one person.
By the way, as a message to everyone, nobody likes it when you generalize religion. Especially when you consider Christianity to be the head of it all.
