I think that boycotting Israeli settlement businesses is a perfectly reasonable response to the illegal occupation, but denying an invidual an academic post because he happens to come from Israel is going a bit (quite a bit) too far in my view. But the case may be more complicated then that. Failure to sponsor, ie- to endorse-- also is a matter of freedom of expression and not taking the positive step of endorsing is a bit different from denying. Let's see how this plays out in the courts.
