We're now into the second and third generations in the UK, and generally the Muslim and Hindu communities have remained as two seperate concepts, but the media is still dealing with ethnic relations among South Asians as if the communities shouldn't exists - mostly as if the Hindus are being Islamophobic and the Muslims are the underdog.
In Sri Lanka, where the Hindus and Muslims are identical to their Indian counterparts, the two have explicitly desired to remain two seperate offical ethnicities even into women and gays due to cultural issues. A similar situation exists, albeit informally, throughout large tracts of India where the governent informally treated the two groups as two ethnicities (notbaly all of South India).
I don't really identify with most of Muslim culture. Racism nowadays is also far worse between Hindus and Muslims, than between Hindus and whites or Hindus and Blacks. Even the majority of 'assimilated' Muslim communities in the UK don't mix with Hindus because we live in different areas usually.
