Even when people don't focus on religion, as it's traditionally thought.
Society, government, laws,
Spend a lot of time telling others how to live their lives.
Dismissing religion, doesn't dismiss the fact that humans place value judgements, in existence.
And being that values are subjective,
Being that it's often 'painful to see people follow or inflict values upon others, that we find 'wrong.
Existence is going to have a lot of people, telling others how to live their lives.
. . .
'Even if everyone destroyed theistic religions in society and history, became atheists, destroyed atheistic religions from society and history.
Religion would 'still exist, in all but name.
And variations would 'still be created anew.
Religion would return.
