The issue/position/argument convention relies on keeping a neutral issue statement and rational arguments, and even most position statements, free of overly loaded terms. Like those that keep showing up in the MemeTank.
Such terms are incompatible in principle with Wikipedia and other GFDL corpus namespace naming conventions as article names: they will always slant the point of view by title alone. To leave them in main namespace is therefore to turn the main namespace into a MemeTank. Argh. If you wish to see this happening, look at term:Islamism, term:Islamofascism, etc., and notice that bad articles crop up there that crowd out good neutral ones.
