Funny, I'm of the opinion they should do the opposite, finally admit once and for all that Starfleet is a military, with maybe some kind of lip service about propaganda claiming they aren't.
But as a compromise, I'll agree that if they want us to believe Starfleet to be purely peaceful explorers they should drop the militaristic side that's been prominent in all the Treks. If they're going to keep that in, than they really should just admit Starfleet is a military. As it is, it's only those who believe in strict 100% adherence to on screen canon with no wiggle room, or the truly devout to "Gene's vision" who don't see Starfleet as military anyway. Hell, Roddenberry was fine with Starfleet being a military until it came time for him to discredit Nick Meyer and Harve Bennett, and then later began hating the military for some reason.
