Afghanistan is one messed up place. I don't see why there would be that many Hindus there anyway. Either those are the extremely poor Hindus who can't make it to India or some real rich ones who are making a killing there in Afghanistan. I suppose this does have a feel of Nazi Germany but nothing to worry about since they really don't have much power except with the fundamentalists.
Yup, that is disturbing. Much of the rest of the Muslim world is pretty extreme already, but none have gone as far as that. I think a major concern will be that other Muslim nations may try the same thing, in an exercise of religious one-upmanship.
