Remember one thing,there is saying that if u spit on to sky ,its only gonna fall on u.So no amout of degrading can reduce the status of Hinduism.When many century of foriegn rule cann dampen Hinduism,how some critism of some lunatic fellow gonna hurt Hinduism.
Finally Hinduism is less about religion more about the spritual well being.Its essentially liberal & accommodating in its way of life .If we change that wat'll be the difference between us & fundamentalist of other sects.
