Right around the time when the so-called "greatest" generation and the silent generation electorally told liberal Democrats to go fuck themselves and die, over several consecutive elections in which the baby boomers sleepwalked just like all the non-voting idiots of today.
They ripped what was left of it out in 2016 and then Performed a complete vivisection in 2020 to make sure they didnt miss any remnants in any crevices as so they could ensure their neo liberal illusion of democracy could continue the class dictatorship their billionaire wall street military and prison industry profiteer donors paid for so they would be appeased and wouldn't cut off their funding.
