Observation of seventy-one years: Every "good" person I know is religious. These are people who are kind, considerate, generous (of time, money, and stuff) to relatives, neighbors, and strangers.
It doesn't really matter what religion they practice, but good people are generally religious. Conversely, not all religious people are "good."
Irreligious people are, more often than not, selfish, self-interested, and narcissistic, not to mention creative in coming up with reasons why they abhor religion. Which doesn't make them "smart" just slightly clever. Irreligious people of the Left treasure the delusion that when they vote for politicians who shower the "needy" with money and stuff, THEY are manifesting their own generosity. This delusion is despicable, in my opinion.
