No one is trying to convince you of anything. You had one reaction and opinion of the episode, and other people, including myself, had another. You would be making a good point with the Cardassians, the Romulans, and the Borg if most of the best races and heros in Trek history weren’t also cast using white actors. The trick of trying to create a “made up” issue by only specifying only half of it is always interesting to me.
IMO, the episode had racially insensitive themes, and if anyone is trying to convince me otherwise, it’s because they want
justifications for their feelings. I just felt like maybe I could give a little of the disregarding of anyone that had a different reaction back to you.
“Myth,” and “much ado about nothing” are also opinions of yours based off of your experience. The fact that you actually think that they were “cool” says enough to me. When anyone can take the offense that a number of people had to the same thing for the same reasons and waive it off as “watering down” racism and what’s racist, that is very sad to me because it says they are not very open to how other people experience things. And it’s when we are not open to how other people experience the world that things like “sexism,” “racism,” “homophobia,” etc. have the greatest likelihood of carrying on. Just my opinion, of course. Take it if you will.
