Remember remember, the fifth of November is a line from the film "V for Vendetta" that always jumps to my mind whenever Guy Fawkes night is close by. And although I rather sympathize with the message of standing up to the "Man", I do not agree with Guy Fawkes' solution. Blowing up the Parliament, government and King with it, is in it self a fascist act: I don't agree with them, and so they must die. Not to say, of course, that it is an act of terrorism.
In this terrorism frightened era, it strikes me as very odd that the British culture should celebrate an act of terrorism, and a failed one as it is the case. But history and cultural memory will always play these tricks on the present. People remember only what they want.
