Far from being progressive, BDS is censorious, effectively silencing Israeli universities by repelling their academics from the West. It is shot through with ugly double standards, so that Israeli artists are harried in a way that artists from China or Zimbabwe never are. And worst of all it has ugly echoes of that darkest moment in European history, when Jewish produce was boycotted and Jewish books were burnt by Europeans who also considered themselves good citizens taking a stand against a problematic, polluting people whose things and ideas threatened European values.
