How is Islam not a racist religion even though it values the prophetâs tribe more than others?

Islam tells us to give extra respect to seyeds, who are from the holy prophetâs family tree and thus are from the Hashemite tribe. Other than that, when it comes to seyeds, there are special rules for them, eg. They get a special share from khums or they donât get treated the same as the rest in doomsday.

That said, how can islam be a religion of equal rights?
