It is used ti be always religion. But now downsides are well understood. And alternatives that can fill the same need (social activities) - like gathering with your neighbors, singing, performing arts, clubs, parks and paries are available and great.

Religions have multitudes of problems but suicide rates amongst atheists is higher than you'd think it would be. It seems like for many, rejection of organized religion leads to adoption of ad hoc quasi-religions with no mooring to them, leaving the person who is seeking a solid belief system drifting until they find a cult, give in to madness that causes self-harm, or adopt their own system of belief that they then need to vigorously protect from other beliefs.

Some percentage of the population has a lesser need for a belief system (supernatural, ad hoc, or anything else) but in general, most humans appear to be hardcoded for this need and the overlap doesn't align strictly with atheism. For the atheist with a deep need for something to believe in, the results can be ugly. Though far from perfect, organized religions tend to weed out their most destructive beliefs or end up getting squashed by adherents of other belief systems that are less internally destructive.

I can see that. There’s definitely a reason they keep pumping out Call of Duty’s and Madden’s.
