I’m addressing all the claims.

You mention Frodo is exactly the kind of reluctant hero the text talks about. Really? The brotherhood of the ring starts exactly when nobody is expecting or asking Frodo to step up, and he, a little hobbit, shouts above a fighting crowd : “I will take the ring to Mordor!”.

That didn't happen in the book. Everyone is silent and eventually Frodo speaks up with dread and a feeling of inevitability.
