White Supremacists, for example, use selectivist Bible scripture to support their ideology. Radical gay/les also use the Bible, selectively and out of context, to support their own ideology. You aren't familiar with the various "liberal" clergy organizations? Or "liberal" churches?
These, I've written of above, ARE the radical, radical right to the radical, radical left.
No need for you to be sorry for what you don't know.
Those are not members of the Evangelical Christian movement at all. They are not even Christian for the most part any more than Jim Jones was. LOL.
