We all recall how South Africa was completely destroyed by of that boycott movement

Tom Friedman Unit starts his column with this:

Israel has recently been under intense criticism on the world stage. Some of it, like the “boycott, divestment, sanctions” (B.D.S.) campaign, is a campus movement to destroy Israel masquerading as a political critique.

I don't think that Friedman's opinion is all that important, but his characterization of the BDS movement is relatively widely held, at least in some circles. So what is the actual evidence that BDS is a campaign to "destroy Israel" as opposed to a campaign to criticize the country and to ultimately force it to adopt different policies?

I want something more than nutpicking (or maybe that's all there is?) I am just trying to get some idea why so many anti-BDS people see the movement that way--if there is anything more to it than just a knee jerk reaction by partisans against anything they view as "anti-Israel."
