And let me add this..............
Let's say in late season 3 of TOS it was revealed that Uhura--the only black regular character---had been born defective mentally and had required outlawed genetic engineering to be fit for Starfleet service. (Oh yeah and her dad was a loser con-man)
Do you honestly think that wouldn't have both pulled the rug out from under her character and insulted/hurt the black youngsters who looked up to her?
If you say, "no, it wouldn't have done that."----
you are a liar or stupid----in my humble opinion.
TOS did something very much equivalent and even worse IMO, in the Nomad episode. They have Uhura recite dialogue fit only for a pre-school child, in the exact same way that a pre-school child would recite it, and they also act like it's no big deal that Uhura's entire identity has been erased.
Are you outraged about the racist connotations of that too?
