abstract
We propose a left-right model of quarks and leptons based on the gauge group $SU(3)_C \times SU(2)_L \times SU(2)_R \times U(1)_{B-L}$, where the scalar sector consists of only two doublets: (1,2,1,1) and (1,1,2,1). As a result, any fermion mass, whether it be Majorana or Dirac, must come from dimension-five operators. This allows us to have a common view of quark and lepton masses, including the smallness of Majorana neutrino masses as the consequence of a double seesaw mechanism.

Dirac neutrinos in a $SU(2)$ left-right symmetric model
An SU(2)_L x SU(2)_R x U(1)_{B-L} model with two or three scalar bidoublets and two doublets keeps neutrinos Dirac and aims to remove the small-mass fine-tuning with a third bidoublet.
