Religion
In reply to the discussion: Once Again, Christianity is a Minority Religion [View all]we haven't had a myriad number of folks look at this from psychologists and ethicists, over literally centuries.
So basically this is one of those silly no one can know what moral is because it's all subjective trains you are traveling on.
There are all sorts of moralities that humans have pretty broad agreement on. Don't steal except in narrow, life-threatening circumstances, don't commit murder with a few exceptions like self-defense, defense of others. We have centuries and centuries of experience coming up with detailed and complex laws (aka moral rules) that look pretty similar whether in the US or Russia or Zimbabwe for the most part.
You seem to have hooked onto the few thorny areas where humans disagree as somehow evidence that one said is "behaving badly."
I don't think someone who is anti-abortion is "behaving badly." I think they are wrong, I disagree with them. That doesn't make their actions immoral, it doesn't make them "doing wrong."
There's a reason why gay marriage so quickly became "no big deal." Because people who had no experience with gay people started to be confronted with the harm homophobia and unequal treatment was doing and on at least some level, said, I don't want to be a part of that. And thus in a very, very short period of time gay marriage became the norm, in fact, the law.
That doesn't happen without recognition that prior positions were wrong, poorly thought out, or the ramifications not understood.
the giant blinding point you miss is that EVERYONE disagrees to some extent about what "good" and "bad" is. You have atheists who are libertarians and advocate for a world that I don't agree with and you have other atheists who are socialists who advocate for a world I agree with more or communists who advocate for a world I don't agree with.
That doesn't mean that any of them are "behaving badly" solely because they have beliefs different from me.
But apparently, for you, that's what "behaving badly" means which suggests you think the vast majority of humans behave badly.
