None of this counters the fact that blaming somebody attracts more flies than not blaming somebody. That's the appeal of most religions. Nobody is going to flock to a religion that has intuitive rules; I could have thought of those rules on my own. To get support, you need to make up a whole new set of rules. The rules must be counter-intuitive so that people who have never heard of this religion would obviously never follow those rules. That way you can point at them and label them as the bad guys.
Example:
Catholic church says it's evil to have sex with people you love. You're only allowed to have sex with the person you are married to, and that's for life. If you have 10 girlfriends and you love all of them, you can't sleep with all of them. This is counter-intuitive. Your dick wants sex because that's how reproduction works. Your brain wants sex because sex is intimate and humans are social animals like that. By setting the rules in opposition to your instincts, it means everybody who is not part of this religion will be breaking the rules. Then you can label them as the cause of problems because suddenly they are different from you.
I can't remember which comedian said it, but this is sort of the logic behind the term "white trash". When there's no specific race or ethnic group to blame, separate white people into groups who are "trash" and not trash, then blame all of the problems on the trash.
