I am Israeli and living in Israel and have many right wing friends, and I don't think it's acceptable or the norm to talk about Palestinian Arabs in this way. I don't hear it, and I am even skeptical that this whole ordeal is not some kind of hoax. This is all painting a picture that Israelis spend their time oppressing Arabs on a daily basis.
