1. Should Gun/Politics be moved to Gun Politics? I think so, because then we can have a Gun Politics/Talk page instead of this Gun/Talk page. Also, Gun Politics is a sufficiently standalone topic to deserve a page.
2. What would an ideal Gun Politics page be like? I think that it is fairly clear that it should present the debate without appearing to take sides in the debate. This will be hard. If someone posts things like "Any additional gun in a tense situation adds to the odds of a fatality" I will have to delete it, because that's just simplistic misconception. But will my deletion be viewed as mere partisanship? I can see why it would be.
3. A comprehensive treatment of the topic, so that people from whatever perspective will leave our section more informed, will cover a wide range of areas. Gun Politics/United States Court Cases, Gun Politics/Accident Statistics, Gun Politics/Assault Weapons are a few of the topics I can think of, each of which might need full treatment in due course. I fear that only pro-gun people (like me) care enough about this stuff to write the pages: but can we write them fairly and objectively? Obviously, I think it is possible, but I readily acknowledge the challenge before us.
The factual stuff (court cases, statistics, etc.) can be moved to Gun/Politics.
Well for some very good reasons, hierarchy is limited to two levels. I don't think that's going to change.
