Good question howevere a name can be integral part of a particular way of life. A way of life represents a culture and how you name and on what names are based are part of culture. A language and literatures are probably most important part of a culture and they shape the opinions on which people name their kids. Michael Porter would be alien to this culture.
John Abraham would also be an alien name? Shah Nawaz Khan? Jeje Lalpekhua? These names are not exceptions by the way. Their would be many others with such names.
A culture is bigger than just some specific type of names. If Hinduism is a way of life then these three names above would be a part of it as they are all Indian with a shared culture. And that is the diversity of Hinduism as a culture. Those ex-Muslims were already Hindus by culture. There was hardly a need for conversion.
But the funny thing is that by offering benefits and converting some alleged Bangladeshi Muslims, the right-wing has fallen into its own trap. Its following the methods of the Catholic Church which it so vigorously opposed all these years.
