The truth is that all religions are not the same. All religions do not point to God. All religions do not say that all religions are the same. In fact, some religions do not even believe in God. At the heart of every religion is an uncompromising commitment to a particular way of defining who God is or is not. Buddhism, for example, was based on Buddha’s rejection of two of Hinduism’s fundamental doctrines. Islam rejects both Buddhism and Hinduism. So it does no good to put a halo on the notion of tolerance and act as if everything is equally true. In fact, even all-inclusive religions such as Bahaism end up being exclusivistic by excluding the exclusivists!
