Ok sure... I can see how /r/baseball is immune from politics. But what about the example I gave, like /r/environment, or even more niche /r/CampingandHiking -- The other day there was story about federal recreation land on there and it was overrun with negative comments for a brief while. So yes, places like /r/programming and /r/netsec is still pretty insular. But it's like asking me to visit a bad neighborhood, because there is a good restaurant there. At some point it's just not worth the risk.
