Earlier quoted context omitted.
I get that, but given the observed existence of a subset of the population where this is currently acceptable, what does "enforcing [] religious or ethical norms" to fix the problem look like? I agree with you there's a societal or communal failure here. I don't see what the solution is (other than jail time/etc).
My immediate answer is to say something like "we need more ethical education" but that's obviously kind of a weak response. The long, slow answer might be that society may re-organize itself into sub-units that do enforce ethical behaviors, and those sub-units eventually prevail over those that don't.
Why do you believe this?
