This is somewhat tongue in cheek, but somewhat serious as well.
First lets put a separate sub forum in the Politics & Elections forum as the BBQ Pit for politics. Any political Pit threads would go there. Normal pit threads about other posters or just rants in general would stay in the regular Pit forum.
Any political comments made in any other forums get whisked to an omnibus political thread in the Politics & Elections forum, no warnings, they just get whisked away. Eventually posters will figure out that that’s where political commentary goes.
It’s similar to what we went through when the original Pit forum was created here. Prior to that, flames against other posters, topics etc. were spread throughout the board. Over time, people learned that there was a special place for flaming each other. It made the rest of the board much more civil. It seems that the politicizing of almost everything has infiltrated itself across the board here. So whisking the political commentary to a forum which already exists for such discussion makes sense
