I think it's the American and British corruption, the murder, the wholesale war for greed and the installation of docile puppets who abuse their citizens.
Some psychopathic elite in America were behind 9/11. This is no longer controversial for those who have the facts. 9/11 was an inside job. Layer upon layer of cover-up only shows that something was being covered up. Too many on Wall Street and in Washington benefited from 9/11. And the government's "conspiracy theory" is full of holes. Take WTC7, for instance. It was the 3rd building to collapse in seconds on 9/11. It fell at perfect free fall for the first 8 floors. Solid steel never offers zero resistance allowing perfect free fall. This means controlled demolition. This means inside job. This means the CIA knew about it, because their 2nd largest office outside of Langley was in WTC7.
What's not to hate. Now, the American government has given Americans plenty to hate -- NDAA 2012 with its indefinite detention clauses for Americans (without phone call, lawyer, trial), HR347 with its criminalization of free speech, and many more marks of tyranny against the new Evil Empire.
And Great Britain is no better.
There are good people in every country and they're all suffering. The psychopathic elite -- the owners of the central banks -- are making it worse for everyone.
