Gandhi never believed in existence of Ram. He believed in Ram - as a character, as a name, and he had his theory of cleanliness of soul through repeatation of prayers and that "Ram" was the shortest form of prayer. Your reference to Gandhi with Ram clearly shows that you are either trying to woo moderates (essentially an attempt to convert them to an extremist) or that you haven't ever read Gandhi himself.
Writing of history has been a tradition in India for years. There are too many too timelines which has no proof. Existence of Ram doesn't mean Ramayana is true, if even Ramayana is real and not myth doesn't mean the bridge is real (and could be re-constructed). If even it was, there is no divinity attached in today's context.
Influence from west or east is not bad. Examples you gave were too rightist -- could be your temporary state of mind, or attempt to woo moderates, or encourage Hindu extremists. As long as the influence does not hurt humanity. Chritanity doesn't believe in science - your knowledge of other religions is at least as poor as that of Hinduism or Gandhi(sm). Those who ruled us believed in science. India believes in science. No one believes and lives by absolute religion, not even Shankaracharya/Pope doesn't. For one you can't because you don't know any religion first-hand.
