I think I would have really enjoyed this episode, as it addressed the only thing in this, one of my favorite shows of all time, that always bothers me - someone finally treated Gary like a human being. That alone should have made the episode one for the books, but instead I was so appalled by what was probably intended as a minor joke that I'm now having trouble mustering up the enthusiasm even to watch the final episodes.
The episode sees the introduction of a men's rights group, the purpose of which is to treat the suggestion of men's rights as an absurd and offensive notion. The group is presented as a combination of weak and basement-dwelling and angry and domineering, presumably because the authors somehow thought that perpetuating all the most popular male stereotypes was the best way to demonstrate that there's no such thing as prejudice against men. The episode concluded the story with the line, "You're ridiculous. Men's rights is nothing."
Whatever your own beliefs, it should at least be disturbing that the writers of a program which has always gone out of its way to be politically and socially open-minded were comfortable being publicly hateful to any group that supports human rights, even if they have doubts about its validity. I'm profoundly dismayed by this display of an attitude which, were it directed at any other group, would be strongly denounced as prejudice.
