It took decades for the Left to gain almost total control over the educational system and entertainment industry and most of the nation's media outlets. This means that younger generations have been gradually indoctrinated to embrace WOKE leftist doctrine for at least the last twenty-five years.
It's going to take a while to both counter their programming -- though simply and relentlessly exposing them to the actual truth about things -- while making sure that future generations are not similarly programmed in leftist ideology at the taxpayers' expense. But it all ties together as a package deal.
