Re: STVI without the racism
Now as for whether the TOS crew was racist against the Klingons in STVI, I would say yes. But again this was the intent of the script even if it did not make sense with earlier stuff from other films and the TV series.
I think it did make sense in context with the TV series. These people were never presented as being perfect they had their flaws and they were always pretty close to the surface.
