The evangelical church in America is being invaded by Leftists. So many churches over this last summer pushed reading lists with books like The Color of Compromise that pushed Critical Race Theory and social justice narratives. These are books written by Leftist political activists posing as theologians. See also “woke” evangelicals like Beth Moore and David Platt
The narrative got corrected too late in 2018 when it got out that it was Obama that set up the cages in 2014. We got more congress people this time and hopefully we’ll get the congress back in 2022.
