Robert Walker 

You were patient on Robert Walker's talk page and tried to be sympathetic to an editor whom you thought was still learning how to use talk pages.  Patience and sympathy are virtues, but he isn't an inexperienced editor who is learning.  He is an editor with a history of excessively long posts to talk pages, who has in the past been taken to ANI for his talk page behavior.  I don't think that he is interested in working on a non-controversial article to learn.  He decides what he wants to work on; he isn't working to learn because he is working to express his views.  I have tried to help him learn in the past, and he hasn't benefited from learning.  Thank you for trying.
