Had a look in the modlog… the mod deleted all comments and locked the thread. Looks really a bit strange. I could understand it as not wanting to attract discussions that could get dirty, at all. Critique ageinst the state of israel is often misinterpreted as antisemitism, and discussions around these topics tend to attract antisemites.
Did you ask why a ban was seen necessary?

I’m somewhat reluctant to post this wisdom here, though …
edit: deleted this comment, as this actually deserves a more in-depth and dedicated post in a more suitable place.
