After banning Martin Himel, whose removal might have been justified due to alleged misrepresentation, PennBDS also revoked Philadelphia's Jewish Exponent's press pass. The crime? Writing stuff they didn't like, such as this article here.
Not surprising. After all, at least in part, BDS is about revoking the rights of Israelis and Zionists, including freedom of speech. If you don't support all Palestinian demands, you will not have a right to be heard anywhere (academic and cultural boycott) or to make a living (economic boycott).
PennBDS organizers claimed they welcome dissenting voices to their conference. Yeah, just don't dissent too much or you'll be kicked out.
