  I cannot speak to the facts of this article. I can suggest that you comment on content, rather than contributors. So try to avoid a personal attack by describing someone else's contribution as a lie. I suggest that you give your comments one more day to see if anyone comments on them. If not, then carefully make the edits to the article, using clear edit summaries to explain each change so they will not appear to be vandalism. Best wishes, and have fun editing.
