Re: Why didn't Chang challenge Gorkon?
Acting like a real person is one thing. Expressing the sentiment that an entire race should go extinct is another. There are a lot of ways to be a believable, flawed human being without ever uttering a word about genocide. They could've had Kirk and the others be uneasy with the prospect of peace without taking it in such a racially oriented direction.
I'll agree with you on this point, as I've often wondered what point Myer was trying to make by including the racism. TUC was released only a few months before the Rodney King Riots happened, so it could easily be used as a social commentary on the necessity of overcoming racism to serve one's country or civilization. But I don't think that's what Meyer was going for. How could he? He wouldn't have known about the riots when writing TUC.
