As an early "Boomer," I vividly recall how radically different we were from our parents (the "Greatest" generation)... and how THEY despaired at the future of the country, if left to us. We also railed against the capitalist system and the horrible consequences of its excesses, from environmental disasters to unjust wars to oppression of minority cultures and developing countries to an insensitivity to the plight of the poor, etc. We started a "countercluture" to replace the tired and narrow minded norms and tastes of our parents, who were appalled by our antics. The best account of this societal/political divide may have been the writings of Norman Mailer, specifically, "The Armies of the Night" and "Miami and the Siege of Chicago," which documented the '60s pseudo-revolution.
So... for those who are overly concerned by the looney tunes of AOC and her twitter minions, it is likely that these shall probably be no more consequential in the long run than were the Chicago Seven or Ken Kesey's Merry Pranksters.
Oh! And Tricky Dick was easily as disturbing a President as is Trump.
