Indian presidents are little more than figureheads, being a cricket team captain has to do with skill not religion.

The Bollywood superstars aren't superstars because they're Muslim, Bollywood is dominated by the on average taller and lighter-skinned Punjabis which make up 1.79% of the Indian population.

And most of the Khans have ancestral roots in Pakistan some of them as far west as KPK, the North-West people of South Asia are seen as physically attractive people and therefore are heavily promoted in Bollywood, they just happen to be Muslims since those areas and their people are Muslim-majority.

It also helps push the state narrative that Indians and Pakistanis are the same people.
