Yeah. It's one thing to say, "what the writers did made me feel insulted" or, "it's like the writers set out to insult the audience," and something entirely different to outright accuse them of premeditation.
Even when they had Kim's parents joking about him not having been promoted, I think the writers thought they were laughing with the members of the audience who thought it was silly that Kim hadn't been promoted, and perhaps didn't realize they were just making themselves look worse in the process...or they were lampshading their own writing choices.
