NuKirk is not about the so-called "flaws." Being cool enough to cheat Kobayashi Maru by nailing a hot chick isn't a flaw, it's a dream come true. Launching a vicious verbal assault to provoke violence isn't a flaw but a necessity to save the Earth at the least, maybe the whole universe by restoring the cosmically necessary Kirk/Spock. Which apparently is why a seemingly random choice of planets provides the future's validation of NuKirk in the nerdgasmic figure of Leonard Nimoy. When God intervenes like that, we surely are dealing with His Only Begotten Son.
The perverse people who couldn't believe that NuKirk and NuSpock could be friends are the insignificant fringe who somehow couldn't thrill to NuKirk's script apotheosis. Or were small-minded enough to find NuKirk's personality unpleasant.
