I don't see how you can expect to not hear the phrase "Gene's vision" in a Trek BBS. Should we just erect JJ-specific Trek hangouts so people like you can avoid Trek purists?
A) We have just such a hangout, it's this forum
and you seem quite fond of hanging out here.
B) My view is that Star Trek isn't a religion with Gene Roddenberry as Moses. Neither we as fans nor Abrams nor anyone else as creators are beholden to "Gene's vision" in any way. As far as I'm concerned, the question of whether or not this or that is in line with "Gene's vision" is akin to wondering if Colonel Sanders 'would have approved' of the Zinger Tower or the Boneless Banquet. No-one cares if he would or not.
Likewise, Roddenberry's been dead for over twenty years. More Star Trek has been made without his involvement than with it. His 'vision' is sweet and all, but it's restrictive of the kind of stories you can tell and the kind of characters you can tell them about. There's just no real reason to keep mindlessly deferring to it, in my view.
