Having gone through a long, long healing process from personal trauma, I'm not seeing "half" as an overstatement. I'm not a psychiatrist, but I see too many people with errant thinking--because they are hanging on to a psyche that is, to some degree, counter productive. BTW, I don't consider myself fully cured.
As the essay has so well alluded, what is normal is often directly or indirectly defined by society. Some religions really need to be challenged in their benefit to society. But we can't take direct action because of "freedom of religion." Add in "pursuit of happiness," we also can't take direct action of people in a semi-destructive lifestyle.
Having said that, the "religion of capitalism" would have us all as obedient workers and loyal consumers. As if nothing else mattered in our brief existence on Earth.
