In my opinion, finding ways to get members who share certain views to network better within the site.
We're talking about ones that particularly established member have shared that a few others agree with but are still controversial. Separate threads for those viewpoints could be done within the site, and if members aren't partial to it, don't visit it. You can't stop them, but at least they would know ahead of time who and what are going to be in those threads.
For the record, this would not include the boards already in place such as Panafricanism that most already agree on. There might be other things mentioned from a VARIETY of stances that could fit into these categories.
