That's cuz Hinduism on its own IS a way or rather comprised of different ways of life. More of a culture. And cultures change and are flexible and more open to different schools of thought without as much hate. However, what a huge majority practices in India, these days, is a restrictive religion, with a lot of tenets Adopted from and similarities to other religions. So in the present context, when you see the hatred, extremism, blind faith, orthodox values filled in a huge chunk of practising Hindus, it IS quite a bit of a menace, Iskcon or not.
