Muslim and Hindu relation in northern India is always polarized. when I see northern Indian Hindu, he looks more similar to a Muslim to me - he displays his religion and customs everywhere. applicable to Jains and Sikhs as well. So, it is Islamic invaders that shaped the aggressive culture and the polarized nature of north Indian society. we don't see expressive Hindus(although RSS parasites are growing down south) in South India. they don't have closed societies(Mohalla) or Hindu-only/Jain-only apartments and Vegetarian enforcement.
Also, all Muslim communities are not into rioting and medieval values. Look at Shafites of Kerala, Ahmediyyas, Shias,Bohras. only the UP,Bihar,MP Muslims are infamous for this extreme intolerance. two big Islamic seminaries are also incidently in UP - Devband and Bareilvy which is forbidden for India government. fact must be a fact whether it is on internet written by any one.
