Originally described in 2014 as: "typified by libertarian political beliefs, Dawkins- style atheism, vague annoyance that the question of gay rights even comes up, eating paleo, drinking Soylent, calling in rides on Uber, reading lots of blogs, calling American football “sportsball”, getting conspicuously upset about the War on Drugs and the NSA, and listening to filk – but for our current purposes this is a distraction and they can safely be considered part of the Blue Tribe most of the time"
But since then the tech world went off the deep end into anti-wokeness and the left has (rightfully imo) come to resent tech and tech companies so they've moved to be on the side of the "red tribe"
