[WikiEN-l] WikiProjects overriding policy

Here is another case of something I mentioned to this mailing list some time ago: http://en.wikipedia.org/w/index.php?title=User_talk:Timwi&diff=10482142… In a nutshell, the [[Wikipedia:WikiProject UK Parliament constituencies]] wants to add the parenthesis "(UK Parliament constituency)" to all constituency articles, even those that don't have ambiguous names and would therefore -- under the general naming convention rules -- not have the parenthesis. These people feel they're completely in the right because they have a discussion to link to -- a discussion that took place on the WikiProject page. Since such a discussion cannot override a general rule such as the Naming Convention, how do I properly respond to this without causing an edit war (or move war)? Timwi
