Never heard it. Is it a reference to the virus that causes AIDS?
Any proof? There are many books on the subject.
Please share with us your references that prove your statements.
Use google and do a search on the Majority Text and the KJV. One interesting book is "Unholy Hands on the Bible." Published by Sovereign Grace Trust. It offers details on mistranslations and text omissions (in the name of improving the New Testament). Theodore Letis has a number of books as well.
Also try a search on Wescott and Hort. Find out how arrogant they were with their newly invented rules for deciding whether a reading was correct or not.
The first chapter of my book deals with these issues. You can find it at http://thystrongword.0catch.com/
I hope that helps.
