Are all religions the same?

It has always struck me as a lazy way to think. It implies a certain distance being kept from each of the religions being discussed – an ignorance, even. It is hard to study the beliefs of Islam and Christianity, say, without realizing that they involve radically diff erent ways of looking at reality. What similarities they share are really only on the surface. At heart they are totally distinct. Saying all religions are the same is just like saying all Chinese people look the same: it just shows that you’ve never properly got to know any. Spend a decent amount of time with a group of people from any racial background and you won’t think they look the same for very long. The insistence that ‘they’re all the same’ may sound tolerant, but in many cases it is little more than laziness.
