Most Onlyists are liberal when it suits their purpose, conservative when THAT serves their purpose, fundamental when it serves their purpose, or "progressive" when THAT serves their purpose. They waffle more often than a trainload of Bisquick.
Why do they do that? To attempt to make up for their lack of evidence to support their myth. That's evident in this very board; do you see any Onlyists answering any requests for PROOF for their assertions?
I've been dealing with Onlyists & Onlyism for over 20 years, and what amazes me most about them is that they keep claiming to believe a false, man-made doctrine that's been proven wrong in every point. The closest thing this mindset reminds me of is the "Flat-Earth Society", which claims to seriously believe the earth is flat, in the face of the overwhelming evidence proving the earth is a sphere.
To me, ACCURATELY answering the questions of a new believer, or an unsaved person wishing to be saved is far more important than "winning" any debate with other believers, and if I actually thought there was any substance to KJVO, I'd never say a word about. However, seeing the KJVOs' complete lack of evidence supporting their myth, and seeing the great double standard by which they operate, I KNOW KJVO is simply another false "ism" that the devil has been able to work into the Baptist faith & into Christianity in general.
In short, the Onlyist cuts his/her cloth according to the pattern of their audience at any given time, be that audience liberal or conservative. The only thing they don't waffle on is their professed belief in Onlyism, no matter how far they must stretch anything else to make it fit the Onlyist myth.
