PDF is a harbinger of majoritarian tendencies which seem to be gripping the world. Bring a solitary Hindu & Muslim together and they would likely end up being friends, same goes for Indian and Pakistani. Bring a bunch of them together and we have riots. It is just the usual tribal nature, defending the turf, marking boundaries etc - nothing unusual.
Believe me when I say this that the hate present here is trivial in most cases, barring some exceptions like Sarthak Ganguly who may have justification for it.
The real issue in India between Hindus and Muslims - is the politics of division and incitement. Something each and every electoral party practices with great expertise.
@Joe Shearer I refuse to believe that Bhakts and Sanghis genuinely hate Muslims. Hating is just a pass time for their unemployed but semi-literate asses
