I can't say I have ever heard of one denomination trying to convert another by going door to door or even preaching on a street corner.
But there are a pile
of them on the internet. One group calls themselves "Bible Believing Christians" and tend to focus on the fact that if you read a translation of the bible other than
the official King James version then you're going to hell.
The most sensational of these nut jobs is Dial The Truth Ministries (www.av1611.org
). Take a few moments to dull your senses on this pile of crap. And this one too: http://www.biblebelievers.com/
