Does it have to make sense?

I have this irrational thing about posting every day. I'm not quite sure why I do it; it's not like anyone in particular needs me to post, and it's not like I have anything particularly brilliant to write, but I suppose that I must give in to my heart and take up some of your time.
Fortunately, I do have something to write about. Go me.
Several years ago I was in Denver (for reasons that will remain unexplored here), and I happened to be walking on a Shabbos afternoon with a couple of older non-Lubavitchers. This was at a time when Matisyahu was at the height of his powers, and was in fact singing that night at Red Rocks. One of the men started cursing him out, and naturally segued into cursing out Lubavitch in general and the Rebbe in particular. I was (not that I'm not now) a pisher, and said nothing. This went on for a couple minutes, at which point we separated paths. The non-Lubavitcher who remained complimented me on the fact that I didn't say anything, and made the point that with some people there's no use fighting.
Many times over the intervening years I've metaphorically kicked myself in the rear for not responding. Not that I'm a big Matisyahu fan, but the fact that he stood for Chabad at that point meant that I should have said something. Same goes for now with Rubashkin. I don't know whether there's a problem with what they do, and I don't even know if they're Kosher, but by golly I'll defend them against any attacker, merely because they, for better or for worse, represent Lubavitch.
I'm not quite sure what I should have said. The simplest answer would've been, "Shut up." It would probably have been the first time he had heard those words in quite some time, and they would have probably done the trick, if only for a short time. I could have engaged him in a lengthy debate, or possibly just asked him if he'd enjoy me cursing out his Rabbi? Perhaps it was better that I was the one who shut up.

All this reminds me of a story that happened about sixteen years ago. I heard it from Mrs. Chani Wilhelm, wife of the Rosh Yeshiva and daughter of the Rosh, though whether that means it's true or not....
The Australian Chabad community held a Shloshim following Gimmel Tammuz in 1994. That night one of the Lubavitcher women who had attended called up a non-Lubavitch friend to complain that no non-Lubavitchers had come to the event. The friend tried to defend herself, "After all, none of you would come for a Shloshim for the Shach." The Lubavitcher responded, "Aderabe, we'll all be very happy to come to a Shloshim for the Shach. In fact, we eagerly anticipate it!"
