More about the Vulcans.
In general, I'm bemused by the tendency to idealize or romanticize the Vulcans. From where I'm sitting, they were never meant to be role models, but one aspect of humanity taken to an extreme. Indeed, the whole point of the Spock-Kirk-McCoy dynamic was that Spock represented logic, McCoy represented emotion, with Kirk trying to strike the right balance between the two.
Furthermore, Spock's whole character arc over the course of his life is about him embracing his human emotions and recognizing that the Vulcan way--pure logic, repression of emotions--is not enough. That's what his big epiphany in TMP is all about, as he turns away from the Vulcan ideal of Kolinahr to eventually grasp that simple feelings, of the sort that are beyond V'Gr's comprehension, can transcend logic.
And lest I be accused of revisionism, let it be noted that TMP was overseen by Roddenberry himself. And that the novelization, also written by Roddenberry, gave McCoy a whole big speech about how much the Vulcans' obsession with logic has cost them and their culture. The Vulcans are basically a cautionary fable about taking logic and emotional repression too far.
Heck, when it comes to "deconstructing Vulcans," McCoy started that way before ENTERPRISE.
