He was claiming that an article that said "neglect" could be used as a source for a statement that said "discrimination". There were several other such instances of misrepresentation in the past hour alone, during which, among other things, he accused me of making a covert attack on his religion. When I pointed out that neglect should not be paraphrased as 'discrimination', he said they had the same connotation. And you are trying to say that "your inability to comprehend that one word does not mean the same thing as another does not portend well for any article you write" is unacceptable? What is unacceptable about it? Is he not apparently unable to comprehend that the two words are not interchangeable? ("Exploitation, Neglect, etc. are all terms with a negative connotation. Pettifoggery isnt going to change the fact that a spade is a spade") Is that not likely to negatively impact any article he writes? 
And where do you get off telling me how to handle him, or making strange 'warnings'? If you can handle him better, why are you not trying to fix these articles that POV-pushers muck up on a regular basis? An abdication of responsibility that's only made worse by your coming and telling me that you think I am being uncivil when I have made the utmost effort over months to encourage this editor to avoid making personal attacks. I am this close to taking this to AN/I as an unconscionable abuse of admin power.
