Betas are the traditional leftists in the socio-sphere (or whatever) I don't see how people don't see this. Nothing really gets as pure left-wing as Betas. Deltas, the polar opposite- are the moral conservative right-wingers. Again, most "therapy" in the West consists of Deltas trying to tell Betas what to do. Gammas are traditional libertarians and alphas are democratic/a blend of everything else, really. Almost anti-political.

A lot of people think they are liberal when they are really conservative and vice-versa. It's kind of funny. The criteria they base their beliefs on is pretty superficial and shows little respect for the original meaning of the terms.

There are exceptions to this rule, don't get me wrong. But generally I believe it's true.
