"Over 100" complaints filed by a population of ~120,000? Seems like a storm in a teacup. There is a bit of racism against blacks(as there was against Mizrahi Jews, except it was much more serious back then), but it's mostly pretty mild. For an example, during my army service I met my first actual (non-Russian speaking)anti-black racist, and while we let him insult Ethiopians without really criticizing him, no-one ever joined in, because honestly, no-one really cares. I should also mention that there are programs giving scholarships to Ethiopian students, as well as government programs aimed at preserving their culture(I actually got involved in one during a school program), so it's not all one sided. Personally, I think they're mostly decent people, unlike Arab scum.
