The demise of Christian theology in the west, particularly since the 1960s, is a tale of how the left convinced everyone that “protestors are always ‘right’ “ and “change is always ‘progress’ “. Having acquired those memes by indoctrination in other courses, theology students brought them with them, primed and ready to accept “new age” and “Liberation” theology.
Not to mention the rejection of “absolute truth” by the modernists. The demise goes back further to the philosophers like Kant and the influence of Darwin on communists like Lenin who truly began the feminist movement.
