I was expecting a rant about how a lot of popular games are filled with kids (CoD, I'm looking at you). But since those games are rated M anyway... On the point that you are making, Halo had a (sort-of) similar set up (minus the Traveler, etc.). Bungie never used the "F-Bomb", and never have. I found Halo to be very compelling, even without the large amounts of blood and gore in other first person shooters. Destiny does not "need" an M rating, because Bungie know what they are doing.
