I will try to relate this to another forum I am on which revolves around a sport league.
The issue of trolling and flamming became a very real one there so they segregated the forum into "general" and "rivalries" sections. Simply put if a thread was created to annoy or mock a fan base it was moved to rivalries. Now, that section of the forum was insanely toxic and mean spirited. However moving all that bile to a sub section made the general much more positive and easier to moderate. "Take it to rivalries" was the first and last warning of any mod so people knew there was an "unsafe haven" so to speak.
What if we did that? A sub section of all the negative crap on here so various communities felt the general forum was a place of civil reasonable debate and moderators wouldn't silence members, but move threads accordingly.
