Hi, and thanks for message. To avoid any further reversions of the content that you add, you must cite any claims you make, using reliable sources  (This is just to make sure that wikipedia's content isn't complete crap! - See WP:V). I understand that you are personally acquainted with the subject, and although that may be helpful in some instances, such editing is generally discouraged on wiki (see WP:COI for more info). As for the "troll" I suggest that you continue to discuss any potentially controversial changes you make (or that s/he has made) on the article's talk page. This is often more helpful than engaging in an edit war, and allows you to sort out the article's problems through dialogue. If you have any more queries, feel free to message me once more.
