This is exactly what you said in your first notice on my talk page: "If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page."  When I bring this up on your talk page, as you said, you said "please take this up on the article talk page."  Furthermore, there are no "other editors" who think that should be included, just that one IP that added that statement recently.  Do you know anything about German history at all?  Or are you just sitting there with your bot reverting 20 edits a minute without giving it any thought?
