Personally, I'd like to try and reduce the amount of politics overall on the site in the near future. It's tiresome, exhausting, and the source of the large majority of the arguments and problems on the site in general. I don't know if I'll need to try to force that to happen or not—hopefully things will start going back to being relatively boring again.
I agree that some people have trouble discussing politics and that, in turn, this causes problems with moderating a space such as Tildes.
However, I believe that it is important for people to educate themselves and, in this case, discussion could be very helpful.
One way in which this could be accomplished here is that politics be discussed in a framework of academics. For example, we could discuss things such as constitutional law or parliamentary democracy.
This is much in the same way that r/AskBibleScholars approaches the Biblical texts in an academic fashion that examines the texts, archeology, etc.
Basically, discuss politics outside of pop culture.
