I have no issues with religious people. I do however have issues with "missionary" types popping up around people who are vulnerable, trying to convince them with completely baseless claims of wellness.
People that have gone through horrible circumstances can, and often do, benefit greatly from the moral certainty that religion provides.
Individuals love to look at individual bits of morality in said books in a choose your own adventure exploration. As much as the moral certainty says be nice to others, it will also contain many bits that are highly questionable and would deeply conflict with others views.
In general secular psychologists don't come with the violent historical baggage that religions do.
Who cares? It gets drug addicts clean and criminals reformed.
I'd be curious to see the stats on that.
