The fact that religious thought tends to be subverted to defend the status quo is hardly a compelling argument as the same can be said for almost all forms of thought. There is a natural backlash from vested interests against any innovation and religion should not be blamed for having this same tendency. We should however not rule out the need to take a moral approach to some things for example; using stem cells might have huge medical benefits but it still needs to be considered whether it is morally right.
