This is right, but let me be the devil's advocate here: one crucial difference is that American pro-Palestinian academics (which basically means almost all of US academics in humanities etc) at least still invite Israel's Chomsky clones to conferences that they organize, while they would be treated as personae non grata among members of the British National Association of Teachers in Further and Higher Education, notwithstanding these Israeli academics are just as self-loathing anti-Israel as they themselves.
I do also wonder about what this fellow feels about the Sorbonne. Whatever British academics have said, that's nothing compared to the vitriolic hatred they'd get from French academia.
