What are the moral lessons for Bradbury's Fahrenheit 451

1.  Censorship is evil: it is an intrusion on freedom of speech, freedom of the press, and banning books is academic and moral neglect

2.  Books must be protected at all costs: they cannot be changed, amended, rated with labels, stripped or watered down, or sampled.  They must be preserved as a whole to protect the moral integrity of both art and artist.

3.  A government that bans books is a fascist or totalitarian regime whose citizens must band together, rebel, and preserve knowledge and academic freedom.

4.  Nuclear war threatens to destroy the planet.  The only thing worse than a world without books is a world burned to ashes by nuclear warfare.  In the 1950s, nuclear holocaust was a real threat to global annihilation.
