The large majority of those who self-define themselves as Modern Orthodox are left-wing Modern Orthodox (LWMO). The right-wing Modern Orthodox (RWMO), those who fully follow, subscribe to and live the positions of R. Willig and R. Schachter, are a very small minority of the MO world.
Walk into any Yeshivish Shul or Yeshiva or minyan and you’ll find lots of former MO people. Those MO who aren’t left-wing have mostly left the MO world and now associate with the Yeshivish world.
