At least JC is consistent with this, as are people like Carroll, Deutsch and Wallace. I find it harder to deal with people, like Quentin, who are basically dishonest; who claim to be working with Everettian quantum mechanics, but continually introduce ideas from elsewhere -- ideas that have no basis in unitary quantum mechanics.
