the religion will need to change tack and become just a religion, not a doomsday cult.
And yet, JW is a cult, not a religion.
As an ordinary religion they cannot attract those who JW always appealed to - the disenfranchised whose only hope was an inside track with God. Without the cult-y aspects - d-t-d, blood, apocalypse, anti-holidays, apolitical, anti-education - then why be a JW? Why not just be a Protestant and be done with it? That has always been the danger of JWs becoming just a mainstream, vanilla religion. What would be the point?
Without their counter-culture persona, what are they? The most incredibly boring people on earth.
