Damn straight. Now why didn't Columbia tell the Trump administration to fuck off (in court) when they were (pretextually) accused of antisemitism? www.nytimes.com/2026/08/13/u...
Judge Dismisses Trump Administration’s Antisemitism Case Against Harvard

Here is our snack. Every bit of produce came from the garden except for the (spectacular) nectarines, which came from Andy Mariani's orchard. It was delicious.
