It isn't anti-Semitism; it's moral outrage.
When Japanese were targeted, even arrested, following the events at Pearl Harbor, nobody called it anti-Nipponism.
When Germans were targeted after WW2, nobody called it anti-Arianism.
As misguided as these attacks on Jews outside of Israel are, they are not racism but retaliations for crimes against humanity. Israel itself made non-combatants legitimate targets by attacking the UN schools and hospitals and killing children.
