They bought into the "love your enemies" line as also meaning to love God's enemies and all wickedness.
If I really wanted to get schizo about it I have a theory that this stuff really kicked off at the turn of the 20th century when "revivals" erupted all over the place with speaking in tongues and running up and down, hooping and hollering and acting like animals became acceptable in service. This birthed the pentecostal church which then birthed the charismatic which birthed the current NAR.
Every one got more and more into this stuff and claimed all sorts of wild things. Boiled down they are all based on emotion. You go to church get "struck by the spirit" and get an emotional high and then come back Sunday for another high. All this is pushed with rhythmic music to hype you up. Emotional dependency lead to acceptance of emotional appeals from outside the church, i.e. faggots.
I grew up as pentecostal and I felt bad because I never really experienced that "struck" thing. Was I touched emotionally sometimes? Sure, but it was few and far in-between and that generally was during preaching as I reflected on what was done for a wretch such as myself. Anyway back to the point, in some circles you were looked down upon if you never got struck.
