None are more hopelessly enslaved than those who falsely believe they are free. ("Niemand ist mehr Sklave, als der sich für frei hält, ohne es zu sein.") -Johann Wolfgang von Goethe
I hope you realize that "you don't know how enslaved you are" is really a terrible catchphrase for a movement. People just roll their eyes when they hear that. You need to back it up with something they can relate to.
