Re: Which species from Trek do you most identify with?
Primarily Vulcans, for a variety of reasons both good and bad. I (like to think I'm) fairly logical and dispassionate when reasoning (good), but I'm also (mildly) deficient socially - I don't often initiate social interactions and occasionally miss social cues, though less than I used to.
I don't know that I'd call Vulcans socially deficient. They simply manifest social graces differently than most. Only human arrogance would suggest that a behavior different from their own is somehow less socially acceptable.
