It has become much too customary to hear of Jews being attacked from New York to Poland, where two Israeli students were beaten by a grip of Arabs,
After all that the Jews have gone through, to know that they are again being roughened up although not by mobs, but by 1 or 2 people is just not acceptable.
Jews by now must have learned that they have to be prepared for all. It is inconceivable to think that attacks against them are just because of the fact that they are of the Jewish religion.
Learning self defense since early age is necessary and fundamental whether it is Krav Maga or any of the other modalities.
Remember the macho survives as long as the coward lets him.
I encourage all of the public and private schools to dedicate part or all of their PE time for the study of martial arts. This will serve as a deterrent as well as a learning process in the ability to discern how to act or respond in uncivil situations.
