True believers are also true non-believers. Thus, if you truly believe in the Hindu gods, you can't also believe in the Christian or Muslim god. It then becomes a matter of which set of beliefs you espouse, and why. The 'why' is usually due to imprinting, in that your beliefs are the ones you were first introduced to by your family, or close familiarity. This also means there's is very little difference between (say) a devout Christian and a committed Atheist, because the Atheist disbelieves in just one more god than the devout Christian disbelieves in. (To explain, assume there are 453 possible known deities: the Christian does not believe in 452 of those, while the Atheist does not believe in 453 of those.)
