It has confused me why Guy Fawkes Day would be celebrated in England to this day.  Obviously it came about during turbulent times between Catholic and Protestant political tension.  However, it has continued and appears to me to be rather anti-Catholic, even though such religious tension has long since subsided.  Here is the poem that is cited/sung in commemoration of Fawkes' capture:

    Remember, remember the fifth of November,    The gunpowder, treason and plot,    I see of no reason why gunpowder treason    Should ever be forgot.    Guy Fawkes, Guy Fawkes, 'twas his intent    To blow up the King and the Parliament.    Three score barrels of powder below,    Poor old England to overthrow:    By God's providence he was catch'd    With a dark lantern and burning match.    Holloa boys, holloa boys, make the bells ring.    Holloa boys, holloa boys, God save the King!    Hip hip hoorah!

While those are tame, the rest of the rhyme isn't (which you can see here).I read somewhere last night that the full poem is recited on Guy Fawkes Day (granted, the Wikipedia entry states, “traditionally the…verses were also sung, but they have fallen out of favour because of their content”).  I'm guessing this is merely for historical purposes that any modern recitation would continue.  Still, it has kind of rubbed me the wrong way that the capture and death of a person battling against religious suppression should be celebrated for so long.  The latter verse of the poem/song is evidence to the religious basis and sentiment for the event.
