its fair to discuss unintentional antisemitism (and racism, misogyny, transphobia etc.) and i'm all for those discussions.
but admins unilaterally deleting people and ideas from audiences is very different -- that has a chilling effect on speech wherein people see the punishment and are then unsure what can or cannot be said, are afraid of being wrong, maybe question their own ideas or feelings on a given topic. it precludes critical thinking rather than engage in it
