Yeah, I've always found the "Roddenberry's vision is impossible to write for!!!" to be greatly exaggerated. Like really, Kirk and Bones didn't come off as humans? Characters in TNG season 1 were still humans.
He'd meant for humanity to have grown past the problems bothering them in those days, in these days. He didn't want the ship to be filled with petty "unenlightened" drama, but I feel people run with that and take it autistically. I think he just meant that people were enlightened enough to be able to talk problems out, understand each other.
A great contrast is how Picard doesn't let anyone give up on Barklay, vs that Short Trek where the chick is like "He was an idiot. Conversation over." Roddenberry's ideals of behaviour vs modern ideals... sadly.
