I have tried to invent a new term called 'a writer’s religious partiality'. It becomes clear when a writer chooses the names of the characters for most of his stories, novels etc. from his own religion. I think that most of the writers are religiously influenced. When a Muslim writer sits at the desk to write a story, then he thinks about Muslim names for the characters. Similarly, when a Hindu writer decides to write a story, Hindu names appear before his mind; a Christian writer chooses Christian names for his novels, dramas etc. But, sometimes a Muslim, Hindu and Christian writers also choose the characters' names from other religions. However, it happens 'sometimes'. In most of the cases, a writer's religious partiality or attachment becomes clear. I must say that this kind of attachment is normal and accepted by everyone. There is nothing wrong in it because a writer’s religious faith, his upbringing, his own community etc. influence him to choose names from his own religion. I have just tried to invent a term for this kind of observation. That's it. :)
