No. Religious all have one thing in common: they make extraordinary claims without backing them up with extraordinary evidence. It's pretty clear nobody believes in this stuff for any good logical reason; that's why they call it "faith". When people of different faiths are making contradictory baseless claims, of course, they cannot settle their disputes through discussions. What logical argument could be used to persuade one side or the other? The inevitable result for society is one of two things: (1) a society in which people of differing religions openly attack each other, such as Israel, Kashmir or Northern Ireland, or (2) a society in which it is taboo to confront ridiculous beliefs because of some perceived need to be "respectful of people's religions". Neither is desirable. Currently we live in the second type of society. It is okay to ridicule someone's stupidity if they claim that leprechauns exist or that they can fly by flapping their arms, but we can't denounce their stupidity if they think that they can talk with a man who died 2,000 years ago, or that there is a loving god who will torture you for eternity without any chance of forgiveness if you don't believe in him. Religion is a funny thing. It can make millions of perfectly sane people believe things it would be impossible for any single individual to come to believe in unless he was completely insane.
