Yes, the Himejima clan killed off Shuri. However, it wasn't a matter of bigotry, or at least not completely. They feared that the 'tainted' Shuri and 'abomination' that was Akeno would result in them losing the protection of their guardian Zhuque/Suzaku. Rather than bigotry, you could say they were isolationist.
