So what do you think of Spock´s line in the context of this episode? I´m honestly interested in your opinion.
I don't doubt your sincerity. However, I am a little confused about what you are getting at by the question. Throughout the episode Spock is confronted with the problems created by appearances, something which the government uses to stereotype and repress the the Zeons (Xeons?). Although not one of them, he is put into a position to empathize with them.
