Please remember that it is very important to argue facts, not personalities. I appreciate that you have made good faith edits, and we're all here for the same reason - to try to make great articles.

If that isn't possible, then we can ask for further assistance, as the WP:DISPUTE policy explains.

Thank you for your cooperation.
