::Central Semitic and West Semitic are not equal categories. Any classification system that does not recognize an early east-west split (the west including both CS and SS) should not be promoted here because it is simply a fringe opinion. As I said already, there are many isoglosses that group CS and SS together as opposed to ES. I expect you to restore the "West Semitic" category ASP because it is a crucial classification level that exists in the best references dealing with the subject.
