In other words, you want to write essays on how people can have political conversations without being mindkilled?

I don't think it would violate the "no politics" rule. Just please keep it sufficiently meta to avoid mindkilling people reading the essay. So if you give an example of a non-mindkilling political conversation, don't talk about a current day issue. Instead, talk about 17th century France and it's use of mercantilism. How might a king and his advisers come to the best policy decision regarding whether or not to allow free trade with England? If they so choose, people can apply those principles to actual political discussions somewhere other than LW.

That said, I don't think I'd read the essay. I try to avoid politics, meta or otherwise. It does sounding interesting, though. Best of luck with it.

( I hope it's obvious, but just in case... This is just my view, not necessarily an expression of LW policy or consensus.)
