It’s actually the opposite of this, the decline of organized religion or codified senses of morality and the rise of moral relativism has greatly harmed western society, regardless of which religion or objective form of morality we are referring to.
There is no reason for religion to exist. End of the day we are should be raised with the same values and by default we should treat everyone how we want to be treated. Religion is just propaganda. Be a human being and respect and support others
