Heres a good one:
Modern society sucks. Everyone is obsessed with looking the best and all this technology. The world has been overcome with too many cities and too many lights that you can barely even see the stars. Modern society sucks dick, we have ruined the world.
The revolution will be televised.
"So many people live within unhappy circumstances and yet will not take the initiative to change their situation because they are conditioned to a life of security, conformity, and conservatism." - Christopher McCandless
