just a bit of history .. Christians used to be quite fundamentalist in 1700-1800's,, what happened? today 95%Christian's in west do not go to church at all ... Islam is going through that phase now. If you really want Hinduism to prosper ,, make it free. People ultimately always choose free ideas . if you instead become fundamentalist and oppose every other religion .. Hinduism will go to dogs.
Just note,, even the worst criminals in movies are shown praying to god ..
