2. Liberal news runs story saying it
3. Millions of liberals instantly accept the story and regurgitate the narrative to the point that its the hill they're willing to die on with no real grasp as to why.
Nothing ever needs to be vast, it just needs to be said once or twice to get 20 million people on board.
Doesn't even have to have coherency, like the idea that only the police should have guns but the police are racist or the government should have more control over 'hate speech' but while the president is/was/will be a fascist dictator.
