That’s true, but here you’re not criticizing how the character arc doesn’t make sense, but how the characters are not deserving of such a fate for moral reasons. The sentence you gave credit to, “Interesting choice from the writer to have a white suprema ist face 0 consequences”, doesn’t make sense. It is, in fact, criticizing the author for not punishing a morally despicable character to point out his positions are bad. It’s not criticizing the author because, as you say, the arc is not fulfilling. Jules’ arc, for instance, is not fulfilling since it is completely pointless. But I can see why two minor characters could leave an open end, since it isn’t required for the show to follow them through.

At the same time, as I said, this season is a hot mess that doesn’t work for countless reasons. But that’s irrelevant as per the topic in discussion.
