I mean, ethnicity isn’t really a qualification for citizenship. And all countries with an ethnic majority aren’t really obligated to take in people of the same ethnicity. The only country I’ve heard of with such a policy is weirdly enough Israel itself. The other arab countries should take Palestinians in just as an act of morality but this “they don’t because of their race” take is bizarre to me. Its very publicly because they don’t want a sizable chunk of their population to have supported radical governments like hamas (even if most Palestinians don’t and haven’t had the chance to since what is it, 2006?).
