Not only is the definition of antisemitism a field of study, so is the use of racism to describe Israeli policy, attitude, and treatment of Palestinians (so-called). Israelis come in all colors. Palesitinians come in various shades, too. But the actual issues around which things really matter are the ones of land ownership, land occupation, right-of-return (or not).
Israel is a democratic country with all races, all religions, all sexual orientations and variations. and a strong capitalistic economy with some strong socialistic institutions.
Pick any next-door neighbor to Israel and you get dictatorship, monoculture, oppression of women, educational starvation, and civil strife. Big-time.
Yet all this donnybrook about Israeli policy, which is primarily designed to preserve her existence. Piling on to the smallest quarterback in the league because it's the one with the filed teeth. Real brave. Real crazy.
