A mockingbird is repetitive while mocking that which it is repeating.
S0... Operation Mockingbird is designed to repeat ( []00p ) continuously, to the point of brainwashing... negatively rewiring the brain, all while mocking its subject matter, which in this case would be the the people.
Operation Mockingbird then creates new mockingbirds in its subject matter, THE PEOPLE - so that they - now ( []00p ) repeat its message...
Mocking and fighting with those who disagree with it, therefore creating division within the people...
Ultimately, killing 2 birds, with one stone.
