Filmmaker Ken Loach and some others have an article at CiF justifying their boycott of Israel. It doesn't look like a very compelling case to me, and I'm mostly linking for future use.
And also because of the cute coincidence that on the same day they published their screed, Haaretz tells of an Israeli research team which seems to have found an innovative new way to discover lung cancer cheaply and effortlessly at an earlier stage than heretofore possible. (Actually, the news item comes from Reuters, not Haaretz, which means The Guardian also had access to it. Heh). The discovery may yet save thousands of lives, and also reduce some costs of the healthcare system. Not the kind of claim one might make about, say, an artistic film.
So far, so banal. If you don't like Israel, you'll never let the facts confuse you. The funny part about the item is the name of the head of the Israeli research team. One Hossam Haik. I don't know the man, but it doesn't sound like a typical name from the shtetl to me. Hossam: now doesn't that have the ring of an.... Arab name?
Life can be so confusing. What's a poor filmmaker to do?
