Of course, Abbas does support boycotting products from "illegal" Israeli settlements in the West Bank, just not Israel itself. In response to a question, Abbas said:
“No, we do not support the boycott of Israel." “But we ask everyone to boycott the products of the settlements. Because the settlements are in our territories. It is illegal. But we don’t ask anyone to boycott Israel itself. We have relations with Israel, we have mutual recognition of Israel.”
But on the heels of Abbas' anti-boycotting statement comes this: a group of around 5,000 American professors and scholars- members of the American Studies Association- voted 2 to 1 to boycott Israeli professors and academic institutions. The Association of Asian American Studies announced its boycott earlier this year.
Well what do you expect from liberal academia.
