Israel has a special unit to "monitor" organizations that advocate boycott, divestment and sanctions against Israel.

Israel says that this campaign is somehow linked to violent resistance, Palestinians in the West Bank that support that cause are called in for interrogation, apparently to intimidate them.

I don't support a boycott of Israel in general, but I do support a boycott of products made in the Israeli colonies in the West Bank (which violate the treaties that govern military occupation).
