Problem is that political threads are often name calling, eye rolling, one-liners like "You would say that", or "Every frum yid agrees that...", without presentation of ideas, perspectives, evidence. So in that sense the political threads are a kind of fake discussion, not that different from the other joke threads in JS, and might as well remain there.
But maybe there's a place for a more reasoned exchange of ideas, on topics that include politics, frum society, education, science, and the like.
In fact, maybe this should be more than a new board, but a whole new website, which would make it easier to read without those bothersome posts about points, miles and deals. This could be a new business for Dan, and require a slew of new credit cards.
