Hindusim has evolved over time ( for example ban on sati and other similar rituals) and you no longer see caste divisions in upper middle class urban society. Yes there are still pockets in rural India where these diviosn are severe, but that too will eradicate with proper education, which is bound to happen sooner or later.
But what about Islamic fundamentalism, do you think it will stop anyday with its massive patronization from Saudi Arabia, Pakistan etc.
