Are you saying that not everyone knew he was a preacher? I don't have that impression.

I think popular culture considers him an activist first and a preacher incidentally. When people condemn Christian culture and teaching as hateful, they are likely forgetting Dr. King is in the picture.

The trope of a Christian preacher in popular culture resembles Bakker or Osteen more than Rogers or King.

I just learned that he was a preacher.

Other than the adultery, of course.
