It is the same day for a lot of actions and events in our general area, Nazi chuckleheads are one of them! Why they chose Saturday the 19th it is a saturday and it is the start of Passover, this way the keep away a lot of Jewish people who really come out in big numbers and get fucking angry at the Nazis because they were the ones originally affected by them the most, so if you choose a religious holiday in addition to the regular sabbath you will kill a bunch of turn out. While the NSM are morons in most regards they know how to maximize their not getting the shit kicked out of them by Jews!
