  Here we propose models with $SU(2)_L\otimes SU(2)_R\otimes U(1)_{B-L}$
electroweak gauge symmetry in which parity (or charge conjugation) is broken
explicitly and the interactions of left- and right-handed fermions are
completely different from each other at any energy scale. In these sort of
models there is no restoration of parity at high energies. However, as in all
left-right symmetric models, the electroweak charged interactions of quarks and
leptons appear to be only left-handed at low energies, because the right-handed
interactions are suppressed by the mass of the respective charged vector bosons
and/or because these interactions may be much weaker than the left-handed ones.
