Let them form their own liberal Baptist group. They’re just committing suicide. Every single major denomination that has turned liberal...every single one...has declined, while more conservative churches have flourished. After JPII took over the Catholic Church, that faith grew as well.
Reminds me of another good book "Exodus: Why Americans are Fleeing LIberal Churches for conservative Christianity" by David Shiflett.
