It seems I'm late for the party... 
If religion dissolves and the absence of a god is apparent to all...
I guess, dumbasses would still be dumbassas, bullies will still be bullies, gullibility will still exist, nutjobs will still be nutjobs... and normal people will still be normal people.
Nowadays, most follow the law, the civil law, not the law of the holy book. So I anticipate that nothing would happen... maybe a bit less traffic on Monday morning, because people would be more rested from the weekend... on average.
