V for Vendetta wasn't written to sympathize with Al Qaeda or whatever else your brainwashing has resulted in making you believe.
V for Vendetta was originally published between 1982 and 1985.
An extreme fascist single-party state has arisen, called Norsefire, that maintains control of the country through food shortages (arising during the nuclear winter), government-controlled media, secret police, a planned economy, and concentration camps for racial and sexual minorities.
