Okay, I see a problem when the artificial construct of religion is imposed over innate personal morality, especially when that grafted construct is weaker in preventing bad action than the one it’s supplanting.
Anecdote substituting as data, but the underlying construct is sound as anyone who’s familiar with Jehovah’s Witnesses will attest–my former mother-in-law is a JW, used to claim to be one of the anointed before they made her stop professing. Anyway, long and short is that her youngest son was a bit of a wild child, ran around a bit, got his girlfriend knocked up, which led to kid and girlfriend being disfellowshipped. Now, per JW canon and morality, it’s up to the individual conscience of each JW as to just how much shunning they do of family members who get DF’d. Most refrain from “spiritual fellowship” while maintaining a more or less normal family relationship while exhorting the straying sheep to return to the fold.
MIL interpreted this as license to hound and harass that young man and his girlfriend with diatribes and harassment and guilt trips and threats against other family members (some of whom she had a lot of financial and other control of) to enforce her version of how to treat the DF’d couple and other basically insane behavior that I don’t want to get into but the upshot is that her nineteen year old son, finally pushed past his limit and stripped of his whole support system wrote a cryptic note and turned his bedroom wall into a Rorschach with a shotgun, to the consternation of his pregnant girlfriend, who discovered him.
Now one could argue that MIL is just an evil bitch who’d find a way to be evil regardless of what set of imposed morals she follows, and that her own innate set is cataclysmically flawed and you’d probably be right. However, the framework and morality of the JW creed allowed her a justification she wouldn’t have in a religion that doesn’t practice shunning, and which also is less rigorous about separating members from outside influence and support. When she was a hippie chick she was still a manipulative, controlling cunt but it was controlled by the arbitrary social construct of the hippie community which looks askance at outright uncoolness and meanness. Shopping around a bit got her a lovely set of justifications that allowed her much more license to exercise her inner preferences–it wasn’t a coincidence that she ended up as a JW instead of a Unitarian Universalist, y’know? She donned that armor of righteousness, just the way the JW’s reward members most for doing and then she used that license to bend and twist her children to her will, with the most awesome of consequences available to hold over their heads–disapproval of a god is pretty fucking scary to a kid when it’s mom throwing it at you, y’know? The rest of her kids are pretty fucked up too, in different ways but the gist is similar.
So that’s my objection to religion in general–that it provides in general a faultier, more generic, less comprehensive moral code than the one we innately make for ourselves. Then once people convince themselves that any feeling of conflict between their innate morality and the grafted one is just their own imperfection and wickedness rebelling against what’s right–they never think that maybe the rules they’ve embraced might be actually just be totally fucking wrong. Religion says it’s always YOUR fault for any and all conflict–not god’s fault, not the religion’s fault, YOUR fault that you need to fix. You buy that and you’ll do anything the religion brings you to believe–only to the extent that you buy into the religion, believe in your own imperfection and sin and to the extent you don’t trust yourself.
A strong person with a good moral sense and a good support system will balk and rebel at bad attitudes and actions commanded by a religion but a scared or weak person or a person who really wants the excuse can use that justification and rationalization to wholeheartedly carry out wrong actions called for by their religion–sure, it’s what they really wanted to do anyway, but might not have done without this really great excuse. The fact that the religious morality is distanced from the psyche, that it didn’t arise from within but is imposed from without makes it harder to test the axioms–you don’t get that gut feeling that something’s wrong, and if something smells wrong all you can do is just scratch your head and go check out the rulebook to see if you’re in the clear, or ask the priest–if he says you’re golden you can stop worrying, 'cuz your gut is WRONG, y’see.
So it’s not this religion or that religion, it’s just any religion that creates the dichotomy between internal and external morality–Buddhism tells you to look inside and see if you’re okay, whereas most Christian religions just give you a playbook and tell you that as long as you’re toeing the line like a good sheep no further thought is necessary–no matter what they tell you. Islam shares a similar problem. The Bible and Q’uran might be fine by themselves but the priests, pastors, elders and imams can be freaking scary…
