White Christian nationalism repels people from church more than progressive ideas do

Evidence

The convincing research presented in The Flag and the Cross has led me to the following assessment: white Christian nationalism is the greatest threat to the witness of the church in the United States today. It is not, as many white Christian nationalists would contend, Critical Race Theory or the 1619 Project or wokeness that push people away from the church and hinders democracy—white Christian nationalism does that. — Philip S. Gorski and Samuel L. Perry, The Flag and the Cross, 22
