Laugh at the bedwetter Salonistas who tie themselves in knots explaining the logical conclusions of their beliefs. Laugh as these two-dollar pundits discover what happens when everything is a "social construct", and try to explain away the silliness of Rachel Dolezal.
Laugh at the Harvard law professor so divorced from the experience of regular people that he writes think pieces about how bowling leagues can lead to fascism.
Laugh at how they spill endless ink yougogirling a multimillionaire LA endocrine experiment.
Laugh at how the most privileged people in human history status jockey by calibrating the privilege of others and searching for microagressions that mess with their bubble. Laugh at how they hold hashtag signs to appear persecuted while they will never do anything more than express virtual "solidarity" with the truly persecuted who live thousands of miles away.
Laugh at how they turn college campuses into intellectual gulags.
You have no other outlet than laughing, since they won't debate, but turn into the very prim, humorless Church Lady caricature that they imagine they've overcome.
The Atlantic asks why there are no comedians beyond their circle, and that is because the absurd parade that is the news is its own comedy show. You're just not supposed to provide the laugh track.
If you want to laugh, but are afraid to do so because you consider yourself part of their place on the "ideological spectrum" (one of the foundational rubrics of the Spectacle), console yourself by knowing that you are providing them much needed critique, as they won't critique themselves. You will surely make them more honest, and their ideas better. Perhaps they will begin to drift a bit away from identity politics, bedroom issues, congratulating their favorite hip millionaires, and start noticing the Davos world that has replaced the Daddy Warbucks capitalists of old. Perhaps they'll reclaim the good sense of their forebearers, and notice a hollowed out economy, a continued warfare/welfare state, the same military bases in the usual countries, and the continued destruction of the earth.
