actually, no, i don't know of Bono claiming the exclusivity of Jesus. i know of Bono believing in God and looking to Jesus as a model, but i don't know of him asserting the superiority of Christianity over all other religions, and i think he'd object to the phrase "Real Believers" as well, because that phrase is so, so, so dangerous and pretty much why Christians have been killing people for the past 2000 years.
Bono speaks of redemption, and to Christians it can be inferred that he is speaking of redemption through Christ, but it's a logical leap to brandish this comment as proof that Bono is a "True Believer" or a Conservative Christian or thinks that Hindus are totally screwed when they die. you're taking your own understanding of the Bible and shaping Bono's words to fit that. i'm not saying you're right or wrong, but i am saying that you've got to be very careful not to conflate your own (highly contestable) beliefs with Bono's beliefs, and also to recognize that there are many people out there who might very well disagree with you on what it means to be a "True Believer" or even that such a title has any meaning at all, and my guess is that Bono would be one of those people who would object to such a label. your interpretations are no better, and no worse, than anyone else's -- debate them, please, and discuss and learn and share, but don't assume you hold truth and other's don't.
