Most of your statements are nonsense. It'd be nice if you could ratchet up the sense level of your post. One way to dot his would be to stop implicitly redefining words to suit your purposes.
My point is that since we know better, we can't go back to when we didn't.
But that often happens. In Greece, homosexuality was approved. Later, it was stigmatized by society. Now, it's becoming approved again. Societies move back and forth - exactly what you say can't happen.
But whether it is acceptable to act immorally does.
This is nonsense. By definition, it is never acceptable to act immorally. What's changing are
morals. We can literally watch them change before our eyes.
What a society thinks is moral, determines whether it views a particular citizen as moral. As opposed to; what a society THINKS is moral determines what IS moral.
You're asserting two moralities - the morality that is
real, and the "fake" morality that society generates.
But that's exactly my point. To allow that society generates morality
of any kind is to accept
my point, and to contradict the OP of this thread. If society is generating morality, albeit false morality, then society
does generate morality. A society's morals come from the society itself, not from some kind of
real morality that is just
out there.
