My take on this is as follows:
I wholeheartedly ENDORSE acts of retribution against the enemy, be it the politicians, their enforcers of all kinds, or other nefarious groups. We should deliver justice to all who have need of such.
As for the normies - the general atmosphere of terror, combined with attacks on the infrastructure, is more than enough. We can leave the Walmart shootings to others, it's not like there's a shortage of violence-prone people in our countries, many of them courtesy of our friends with small hats and big noses.
