I have met some of the weirder-side Christians over time, but I have yet to encounter one of those sorts you describe. The "you're making me uncomfortable with your goofiness" Christians I have spent time with were almost exclusively NIV readers for some reason. Not sure why.
OK, let me try to remember some of the Weirder-Side Christians I've met. This should be a fun trip down memory lane.
The church we attended when I was a pre-teen/teen was a Charismaniac church. Some members were weirder than others, but I don't remember any particular translation being preferred. Probably NIV was most common, but I'm not really sure.
Some of the people at my current church are distrustful of newer translations, but not necessarily weird. One of our members has a brother that bills himself as an evangelist. When he spoke at our church for a week of revival meetings, every sermon was a detailed road-map through the last days. If I remember correctly, newer perversions of the Bible were on his very long list of tools that were being used to bring us Evangelicals "back" into the Catholic Church of anti-Christ. We probably won't be scheduling him to "evangelize" at our church again.
The day after our wedding we looked for a Sunday morning service to attend, and wound up at a small Baptist church, where the marquee sign read simply "King James Bible." The people seemed nice, and fairly normal, but I do think it is a little weird, just advertising your choice of translation in big letters on your church sign.
I've met enough weird Christians (heck, I am one), but I don't usually ask their opinion on translations. I'm sure it runs the gamut. However, I am quite sure that my chosen translation, the NASB, does not attract any weirdos. None at all.
