I have no idea what the majority of Israelis think about Palestine and Palestinians, but this video is probably just seeking out arseholes to ask their thoughts. Every group of people has arseholes.
I'm British and socialist, but I would think it would be very easy to find 20 minutes of footage with British people saying appalling xenophobic and racist things about just about anyone.
That all said, the people being interviewed in this video are scum.
