I’ve read all of them, and didn’t see anything about race, unless you see Saudi Arabians as a race, specifically the people in power. There are many different Arab peoples with completely different looks and values to Saudi rulers. I see a lot of critical comments about a pervasive patriarchal culture that is consistently and unapologetically misogynistic, actively opposed to equal rights for women (and other marginalized groups), and I don’t see any problem with that kind of criticism in the same way I don’t when it comes up in reference to nations where there isn’t a dominant religious monoculture but still systemic repression of human rights. It’s dangerous to conflate criticism of sexism and theocratic repression with racism.
