I like several of the crazy high concept episodes from later in the series, including "Masks" and "Genesis."
I know huh! Too many black faces onscreen for some whites to handle, right?
Hey, imagine this: What if we had a well-written Star Trek show with a predominantly black cast! I'm sure you - and likeminded individuals - would hate that....! hahaha
This sort of thing is uncalled for. JirinPanthosa
laid out a rather concise version of why the episode is problematic (for a longer version, Daniel Bernardi devotes fifteen pages to the subject in his book
on Star Trek and race, which is worth reading if you really want to do this sort of thing as an academic) and it has nothing to do with fearing a predominantely black cast.
