This is why you don't need both a left and a right-handed spinning degree of freedom to describe these particles. In our standard model, we have left and right-handed degrees of freedom for all of the quarks and the electron and the muon, which is my favorite particle, and the tau. But we do not have that for the neutrinos. For the neutrinos, we only have left-handed field components.
