Liberalism stops being anything like liberality when it doesn’t allow any room for dissent and debate.
It already doesn’t (it’s morphed into leftism, or shown its hole card, one or the other). It can’t defend its ideas, so it tries to suppress the opposition. Or even force the opposition to carry its message for it!
So even as Satan can appear as an Angel of Light, so similarly many wicked men start out pretending to be shepherds caring for hurting & wounded sheep until the opportune time to feed on their growing flocks.
