They got involved in right wing extremist politics, now the "largest Protestant Denomination in America" is dying.

10. Southern Baptist Convention was always divided

There were Fundamentalists. There were Mainstreamers. And there were Scholars.

Owing to political strategizing of Paul Pressler and Paige Patterson (architects of SBC's Conservative Resurgence), the Fundamentalists took over everything.

By the way:
1) Paul Pressler died in disgrace, after it came to light he liked hot-tubbing with naked boys.
2) Paige Patterson was fired (and blacklisted) after allegations he mishandled incidents of sexual assault on the seminary campus where he was president.
3) Patterson also was accused of theft.

Right-Wing Politics and Religious Fundamentalism go hand-in-hand
