I don't think so. It is frustrating that the church does not have a more diverse leadership, but the issue lies more in the past than in the current times. These guys have basically been being groomed to be apostles for at least a decade. There just aren't isn't a lot of diversity in the top levels yet, and it seems it will take some time for that to change. There are a lot of new members of the quorum of the seventy who are from somewhere other than utah or north america, but they have been called to that position relatively recently. It takes time for them to get the experience that others have just by virtue of being in the leadership positions longer.
Those are my thoughts. Maybe I am wrong, but in my mind the alternative is that the old dudes are still racist and they think God never changed his mind about black people.
