Poll: Half of Canadian BDS Supporters Would Continue Boycotting Israel Even If It Agreed to All Their Demands

'Of the 19 percent who expressed support for BDS, 45 percent said Israel should be subject to additional boycotts, even if it abides by all BDS demands — namely, withdrawing from "occupied territories," which were not defined by the poll, but are understood to include eastern Jerusalem, the West Bank, the Golan Heights, and — indirectly — the Gaza Strip.'

Are many of those people really "from the river to the sea" supporters, would Jeremy Corbyn agree?
