Guy Fawkes Night, also known as Gunpowder Treason Day, is a commemoration of the 1605 Gunpowder Plot, in which a group of English Catholics attempted (and failed) to assassinate King James I (a Protestant) in an effort to install a Catholic head of state. (Wikipedia – Guy Fawkes Night)
The thing is, celebrating this day is really itchy. It’s hard to commemorate such an event without seeming to be anti-Protestant (or possibly even anti-Catholic), or endorsing terrorism.
So we’re probably just going to watch V for Vendetta and be done with it, if that’s cool with everyone.
