The cultural tolerence among muslims you see in India is simply a result of the influence of Hinduism.
And not economic developement or influence of the west. Also, most muslims in India, whether they agree or not are recent converts from Hinduism and not descendents of Arabs as many like to believe. So, living among the most peace loving religion (Hinduism having never imposed itself, through violence or conversions on others), they are bound to get influenced. That according to me, does not prove much.
