You know what I really loved about that episode? It doesn't take one side on an issue it's trying to address. Sure homer is portrayed as his usual dumbass self with a gun and Marge is very much against him owning one. But the episode doesn't portray one side as right or wrong. Homer's irresponsible behavior makes a strong argument for gun control but at the same time the other members of the gun club portray the positive side of being a legal and responsible gun owner. They rightfully are outraged when they see how wreckless Homer is and kick him out of the club and even save the day in the end.
If the cartridge family was made today you can bettor would be a one side almost after school special bad episode on par with say.. Lets not be skeletons from okko
