:::Clearly, not carefully enough, as #5 was not "well-sourced". As well, it did not have the "widest support," and furthermore could not be used, as it violated wiki policy, specifically, WP:LEAD and WP:N. I wasn't the only person to point that out, as not only the mediator pointed that out, but others as well, including Agha Nader and myself; it is worth noting that Agha Nader usually disagree rather vehemently on a wide range of topics. That we found agreement on this is significant, and should be telling you something.  
 :::Rather than expend your energies on a choice we cannot use, perhaps you could concentrate your efforts on finding a wiki-allowable solution that everyone could live with. If you are entirely unwilling to pursue such a course of action, I suggest that you re-submit the matter for mediation. I suggested ArbCom as it is sometimes an effective 'court of last recourse'. They can certainly address an unwillingness to follow wiki policy in regards to policy on the part of editors. -
