There in lays the problem: "We want something original and new!...you bastards, you changed Star Trek! Ruined forever! Canon Violation! Canon Violation!"
Imagine the shitstorm had they made Kirk or Spock a woman. Changed Kirk's race, made him black or middle eastern.
"Original and new" doesn't mean politically correct theatrics such as making Kirk black or a woman. It means original story concepts, new ideas for what to do with the characters we already know. Not racebending ( sexbending? ) as a substitute for originality of plot.
