How can there be a God when the sheer evil of the war in Sri Lanka(as shown on channel 4) can happen?

That one is basically Hinduism vs Buddhism. Go to the Catholic section of Belfast and announce that you are a Protestant. You may get a very quick and permanent out of body experience - or visa versa. Also if you go to iran and announce that you are a Bahi, you may quickly find yourself dancing at the end of a rope. Go to Pakistan and be a Sufi, it may not be long before your shrine is blown to pieces by a suicide bomber, with you inside it. Inspiring isn't it.
