I don't think age should be an excuse for dismissing anybody's views.
Oh, I don't think we're dismissing anybody's views. We're just acknowledging that people of different generations are, inevitably, going to have different takes on things--including the inevitability of reboots, or when exactly the glory days of STAR TREK were.
I write TOS books. You prefer DS9 books. Given our respective ages, that's perfectly natural--for both of us.
Where people get into trouble is when they start insisting that their generation of Trek is the "real" Trek--and everything else falls short.
Like I've joked before, fifteen years from now, cranky fans will be pining for the Abrams version--and arguing strenuously that the new, new STAR TREK violates everything that has gone before!
