Blogger and columnist Cathy Young dissects the ideological hypocrisy:
Are these boycotts anti-Semitic? Maybe not, but, as I noted the other day, they are hypocritical, sanctimonious, and deeply wrong. No one is demanding a boycott of Russian academics over Russia's occupation of Chechnya and the atrocities committed there (which dwarf, to put it mildly, Israel's human rights abuses in the occupied territories). Or, as Ari Paul points out in an article at Reason.com, a boycott of Chinese academics because of the occupation of Tibet and other assorted abuses by the Chinese regime. Or ... sadly, the list could go on and on.
Partly, this double standard is rooted in the all-too-familiar leftist mentality which strenuously condemns bad behavior by Western or pro-Western governments while turning a blind eye to the far worse misdeeds of communist and/or Third World regimes. (It's not quite clear into which category Putin's Russia falls.)
