What really sets off leftists in situations like this is when anyone (especially GOP politicos) offers thoughts and prayers to those wounded as well as the loved ones of those killed. In fact, the proggie response to such sentiments is often maniacal and downright hate-filled. Truth be told, I'm past the point of reacting to these people with anger as much as I feel genuinely sorrowful on their behalf. The idea that "progressives" believe a legislative branch of government (comprised of fallible human beings) is better qualified to help a nation heal from a tragedy requires infinitely more faith than seeking guidance from the Lord.
As David French of National Review notes, prayer is not only sufficient, it is downright vital.
It’s as simple as this: God is sovereign, and every good and perfect gift comes from Him. That includes changed hearts. It includes comfort that only He can provide. It includes the courage to be the “good guy with the gun” who can (and, reports suggest, yesterday did) stop a rampage in its tracks. It includes the clear mind to consider and enact policies that might make a difference.
So, yes, if you’re not praying and thinking in response to mass murders like the attack on the First Baptist Church in Sutherland Springs, Texas, your response isn’t as effective as it could be. If there’s one thing that’s clear from the spate of mass killings in the United States, it’s that we need God to move.
I believe it's highly inappropriate to politicize a tragedy in the immediate aftermath if for no other reason than it trivializes someone's death. But above all else, being fueled by raw emotions instead being guided by the steady hand of God leads to regrettable behavior that is neither productive nor comforting.
