Okay, I'll bite.
The "new libs" do not give the first crap about getting along.
One of the first and most effective tools for social cohesion has historically been shared religion. The left demonizes Christianity (Muslims are apparently just fine), and advocated for a godless society (again, except for Allah... he gets a pass) but still expects that with no guiding "divine" principles, we should still internalize the principles without the God-figure. How's that working out?
