So what? How is a Jew threatening other Jews any different than Muslims and Arabs threatening other Muslims and Arabs as they do in Syria, Iraq, Lebanon, Sudan, Nigeria, Yemen, Somalia, etc.?
Only in this case, the Jewish person was arrested and charged, whereas in Syria and Iraq no Muslim or Arab is ever arrested and charged for threatening and, worse yet, killing thousands of other Arabs and Muslims.
Plenty of examples where Israelis have committed crimes against Arabs and have been arrested, charged and convicted. The thousands of Muslims and Arabs that have been killed in Syria, Iran, Nigeria, Sudan, and other Arab and Muslim countries have never been arrested, let alone charged and convicted. Give your head a shake!
