Last week’s killings of two Israeli embassy employees in the name of “Free Palestine” is just another sad example of how the Left has lowered the bar for the justification of political violence. 

Endemic antisemitism continues to spread on college campus across America because the people responsible, DEI proponents and recipients, feel that they are untouchable, argues Victor Davis Hanson on today’s edition of “Victor Davis Hanson: In His Own Words:”  

“So, that is one thing that's happening. And that makes violence more permissible. The other is this endemic antisemitism. Let's be honest. It's not some cowboy in Wyoming in 1950 that doesn't like Jews. We're talking about two nexuses that come together and promulgate antisemitism. The one is wealthy people in the universities—many of them DEI, but not all—who feel that it's either en vogue or, as DEI people, they cannot be criticized as victims for victimizing others, meaning foreign students from the Middle East. And in that cauldron, it becomes permissible to say, “Globalize the intifada,” “River to the sea,” the eliminationist rhetoric about Israel, storm a library, chase Jews into a library, damage the president's office, rough up a Jewish kid on campus. It was all acceptable. There were no consequences. That's why those three college presidents either were fired or had to resign.”
