::::The reason I suggested WP:DRN is that it is a much more structured form of dispute resolution. It's purpose it to deal with seemingly intractable issues like this one in a quasi-formal manner, in a way that just getting the opinion from an outside editor does not. It is not perfect, and it relies on all parties being willing to listen to each other and compromise; however, it has more chance of bringing resolution to this conflict than just continuing the present discussion. If you really think that Mrm7171's behaviour is so problematic that he's disrupting Wikipedia and not working for the good of the project, then I suggest you go to WP:ANI. If you do so, you will need strong evidence to show the disruption caused, and must realise that you behaviour will also be scrutinised.   •
