I already agree that arab culture allows for racism to fester, but why should relinquish support for a palestine because of a racist man? majority of palestinians are teenagers and children, many barely-adult people. As a woman, I've heard somali men say horrible stuff and let's be real, our culture allows for that. So if that's true, why would I support somalia? Because it's my home. And it's the same for me with palestinians. I won't abandon my sisters in palestine because some of them are racist.
Letting genocide commence unchallenged because of racist comments is softie behaviour. We can defend ourselves against racism without abandoning palestinians.
