I didn't find the article particularily humourous (but I'm not a great fan of the Three Stooges either). The analogy is faulty and he repeats the absurd proposition that patriotism means silently surrendering thought and conscience to someone else. If he wanted to make the analogy clearer and funnier with a similar moral he could have suggested:

HOW TO DEAL WITH PEACE ACTIVISTS

With all of this talk of war, many of us will encounter "Peace Activists" who will try and convince us that we must refrain from retaliating against those who terrorized us on September 11, 2001. These activists may be alone or in a gathering; most of us don't know how to react to them. When you come upon one of these people, or one of their allies, here are the proper rules of etiquette: 1. Listen politely while this person explains his or her views. Strike up a conversation, if necessary, and look very interested in their ideas. They will tell you how revenge is immoral and that by attacking the people who did this to us, we will only bring on more violence. They will probably use many arguments ranging from political to religious to humanitarian. 2. In the middle of their remarks, without any warning, punch them in the nose. 3. Immediately render yourself unconscious by hitting yourself on the head with a frying pan (red-hot "patriots" have the option here of shooting themselves in the head instead). 4. When the person gets up off the ground, they will be very angry, and they may try to hit you, but you won't know because you will be unconscious and defenseless. 5. When you come three, sorry, to. Try to discover if the pacifist either kicked you while you were down or, finding you unconscious and unable to respond, ran around hitting street people, beggars etc. who look like you. 6. If the pacifist didn't do either of these things sit down and hurt your head again by thinking about why. 7. There is a distinct possibilty that the pacifist will realize that he/she was dealing with a mentally disordered person and will have kindly taken you to a hospital. Smile nicely at all the people in white coats, take all the pretty coloured pills that they give you and say it is because YOU are a true patriot and love America.
