Wasn't there a less passive-aggressive way of expressing this complaint, or a more appropriate context for it?

Please link to a few examples of where this has been successful.

I for one would appreciate it if the discussions of geopolitics, immigration policy, monetary policy, factional and sectional politics, adherence to various national leaders — and anything else about "Us vs. Them" where "Us" and "Them" are defined by which section of Spaceship Earth the parties happen to have spawned in, — would kindly fuck off back to the comments sections of newspaper websites or some other appropriate forums.

The idea of LW as an explicitly Enlightenment project, one that actually contemplates ideas such as "the coherent extrapolated volition of humankind," "applying the discovery of biases to improve our thinking," and "refining the art of human rationality," is something rare and valuable.

Yet another politics comment section, another outrage amplifier, is not.
