I don't need to defend the honor of my religion to keep it.
Then good for you. I'll try to explain what I mean.
If Moses did not actually part the Red Sea, if it turns out that the Jews never congregated at Mount Sinai and that the Ten Commandments were made up by Moses, if it turns out that Christ never actually performed any miracles and wasn't crucified, or if it turns out that Mohammed did something - anything - wrong, or made a mistake in the Quran, it's a big "GAME OVER" for the respective religions. The entire basis goes away. They break down.
This is not the case with the Hindu traditions. Even if it turns out that the Puranic accounts are complete fabrications, if it turns out that the epics consist almost entirely of embellishments, even if it turns out that Krishna or Rama didn't actually ever exist, the tradition will remain almost completely unaffected.
This is because it is philosophy which is the basis of the tradition, not faith or history. Philosophy is self-sufficient, not needing any external validation, and open to experience. If a better, more coherent, and more powerful and constructive philosophy comes along, the new takes over the old, and the tradition changes accordingly.
I also don't need to investigate the truth claims of all faiths in order not to accept them. I don't explicitly reject most religions, I essentially take an agnostic approach.
Again, you do the only sensible thing, given the circumstances.
