Dear Rehana Khan, we can certainly restrict our religious beliefs to our homes and interact with the members of other communities in a secular manner. The so-called holy books are creations of surrealistic visionaries and are no more serious than Gulliver's Travels, Aesop's Fables, Panchatantra or Mulla Naziruddin Stories! The religions and gods are inventions of vested interests to further their selfish motives.
