Before the last American election there were several long threads on American politics. For what it is worth, despite that I did not engaged myself in these threads, I have learned a lot from them about the U.S. and Americans in general from reading parts of those threads. Media of course covered the elections a lot over here, but if ever "normal" individuals are interviewed it's for a few seconds in a news broadcast, which gives very little. Being a scientist active in research, I do have some American colleagues that I know well enough to get a bit of their view on politics, but then I never trust them to be representative since we scientist seams to be a bit of an international sub community that has so much in common whereever we are. So it has been very interresting to me to read about the political views from people with very different background with nothing in common besides having a Pentax (which I don't think bias the political ideas). Since some non-U.S. citizens also engaged in those threads it may be that some of you Americans also learned a bit of how others look at you (?). Though the American election is a good example, there are other subjects, for example current economical problems, that has given the same valuable insights. I would find it sad if this possibility would be removed, though I can understand that those discussions that go wrong is a pain for Adam and the moderators.
Another thing is that I'm wondering how you will draw the line. Say that a thread starts on the current lack of new offerings from all DSLR manufacturers, Pentax in particular, someone will say that it is not surprising since the economics is so bad, and from the current economical situation we are just a few posts away from politics and this may even in some sence be relevant for a camera discussion. It is easy to think of other difficult cases: say that someone post pictures that show poor people living on the streets...only a post away from politics. Or the important matter of how photographers are treated by the police...only a post away from politics. In some sence, everything is politics, not party-politics, but politics in some way.
Religion...how will you deal with the not so small group who appear to worship their lenses???
