I think you've just defined faith, and you appear to have defined it as something totally insulated from the world of reality.

Rather, you have defined scientifically-detectable reality as the only reality. Which, as I said above, you cannot do via science. You believe this independent of scientific evidence, for "science" is a scientific entity.

If believers don't need 'scientific evidence' for their belief, why should they bother about it?

Because there are more things in heaven and earth, Horatio, than are dreamed of in your science.

I was willing to overlook the Romans with an artist's prerogative but I beg to differ with any assertion that Hinduism today is a violent religion.

Whoa, where did "today" come from? You're moving the goalposts. What about Alexander the Great?
