Anthony Bradley talks about the rap song “Precious Puritans” by Propaganda. He explains how the song criticizes puritans for condone slavery (which frankly is news to me and troubling), but goes on to say he, the singer, is no better. We all have flaws and blind spots.
However, by singing about puritans in an unflattering way Propaganda has raised the ire of many reformed writers. Bradley suggests this may be typical tribal thinking.

Strachan considers the Puritans “forefathers” and in a tribalist way, some would argue, seeks to protect their legacy. Had Propaganda dropped a track critiquing Roman Catholics, Jeremiah Wright, Rob Bell, Brian McLaren, or preachers of the prosperity gospel, he’d be called a hero. During my seminary years I was rebuked once for mentioning Martin Luther King Jr. in a sermon because of his sins. Why? Because King, like the others, are outside the tribe and are fair game to be critiqued in any form. Since they are not “one of us” there is no expectation of extending grace. Grace is reserved for those with whom we agree.
