"Critics of “progressive Christians” often describe them as moral relativists who lack objective, universal Truths and accept all beliefs, behavior, and lifestyles regardless of sinfulness."
It's not at all clear to me why the hell we progressive Christians should give a tinker's damn about white "christian" nationalist "critics".
Should BLM activists and allies put energy into defending themselves against KKK and Proud Boy critics? Should PFLAG members respond to Westboro Baptists?
Trust me, I've NEVER felt myself to be "on the defensive" with respect to the racist, fascist, hate-filled, black-hearted bigots who use a deeply evil theology to cover their many and horrid sins.
