Academic boycott

A few days ago I read about the renewal of an academic boycott on Israel by the British academics and I fail to follow the logic of it. Not only it attacks the sector which probably holds the most liberal views and is promoting a leftist agenda, the argumentation provided is so lousy, stereotypical and blindfolded, that it crates an obstacle by itself towards any kind of dialogue. There was an article in the Hebrew version of Haaretz today, which made me wonder, how many of those who so passionately advocate such boycott (it is already the second large scale attempt) do really understand what is going on here? Is any idea, articulated strongly enough able to carry away even the very intelligent groups of European academics without trying to go into the depth of it? Weird feeling… Still thinking about it…
