Everyone has their own ways.
Yes, but not all ways are equally healthy. If you need to believe in falsehoods to be happy in life, that’s objectively a less productive coping skill than one that doesn’t involve that. Personally, as a society, I strongly feel we should be setting the bar higher. It should be an embarrassment to have such beliefs.
Mind you, I would never an am not advocating anything like legislature to enforce anything. Cultural change can’t be legislated. I just firmly believe in such change.
