Wrong.
Some religions are inherently a problem. Most aren't. It's the practiioners. Most religions don't fail, people fail.
Christianity, for instance, is an enormous cause of human suffering because Christians do not practice Christ's teachings. There is no doubt Christ would disown most people who call themselves Christian. Compare, for instance, Bush's actions with "The Sermon on the Mount". What about his driving the money-changers out of the temple?
Buddhism isn't a problem, and the people who try to practice it can be wrong.
