I think it funny to characterize Mohler, Moore, and Greear as "Liberal." They are anything but. I am a Southern Baptist, but I do not walk lock-step with the denomination. Some things the denomination does frustrates me to no end. However... there is a BIG difference between what should rightly be called the "Traditionalists" and the "Biblicists." (Yes, I know traditionalists will object to the uses of biblicist, but grant it for the sake of argument).
Mohler et al. are in many, though not all, cases far more biblical than the Traditionalists (Trad). And if the Trads feel threatened by the biblicity of the Biblicists, welll, of course they are going to be labeled as "Liberal."
