I’ve never met a Christian who followed them any more than any atheists I have met tbh. Perhaps I am just unlucky or perhaps people behave entirely the same way regardless of religion.
And what about women not being allowed to talk in Church in Paul’s works, having to cover their heads etc, and about 300 seperate laws in the New and old testament I don’t want to go into.
Like I say some so called rules are timeless and hardly Christian in origin. However some bigotry and intolerance results from taking the words of people who only meant to direct Christians in the fledgling Church and transplanting it to modern conventions as if somehow Jesus himself said them. This is redundant. Sure go with what Jesus said but what Paul said was meant for his fledgling church not all mankind forever, he didn’t have the right and was never accorded the status of a prophet who spoke for God.
No doubt if he were alive he would of been appalled at the idea that he was speaking directly for God except in various visions perhaps, such an arrogant imposition would of been blasphemy to him.
The moral behaviour of Christians in my experience is no more or less superior than any other persons, Christian, religious or not.
We all have our morale codes most of them are enshrined by law, some by social convention and some by personal credo.
There are and have been plenty of evil Christians and plenty of evil atheists, religion historically seems to make no real difference.
