Many of those in these campus demonstrations are themselves Jewish.
I honestly believe it's a form of intimidation that makes them do what seems strange, supporting a cause that wished them dead. Because once these useful idiots are no longer needed, that is exactly what they be if they refuse to convert.
Even conversion is often futile. Stalin killed off most of the Jewish Communists and Stalin did the same with the Jewish would-be NAZIs though earlier in the process.
