Here's an additional suggestion. The Re-Birth of RGP, (Rec Games Pinball).
RGP is an old Google group for pinball that has been abandoned in favor of Pinside. It has ZERO moderators there and it's a Pinball forum. It's easy to join with an email and you obsessed, political instigators could live the remainder of your lives there.
Someone could begin a thread and call it whatever you like. "Pinside Democrats V Republicans", for example.
