First of all Hindusim is not a religion but rather than a way of living if you are aware of. You call Indian muslims as cowards when the truth is that Hindus were subjugated beyond comprehension in the past by the muslims. not only that Hindus used to offer their daughters in marriage to muslims in order to appease them. Even the myth of rajput bravery was broken to pieces from time to time by the muslims. Second muslims dont go to church because they have firm belief in their faith, having one color but not changing colors from time to time.
