The author has identified the essential difference between leftists and conservatives. Put another way, conservatives fear God and leftists would be God.
The ineffable reality of faith is that it performs contrary to leftist expectations about believers, it does not put them in chains, it liberates them. The other side of the coin, hubris, the drive to play God enervates the individual, sucks him into the collective, and ultimately destroys him. Finally, it enslaves all those about him whom it does not destroy.
Well put.
