Why does Anonymous and anarchist groups use Guy Fawkes as their symbol?
Guy Fawkes was a Catholic extremist whose only motive was to kill the prodestant King James, ths resulting in Elizabeth ascending the throne in order to establish Catholic dominion in England. While the reign of James was discriminatory to non-prodestants, the plot Fawkes was doing the dirty work for (he was not involved in the planning or scheming, only carried out orders) was far from fighting for freedom. Since King James was generally well-liked by his people the 5th of November became a holiday were people would burn effigies of Fawkes and the Pope to symbolize that their country would not submit to Catholic rule.
So what Guy Fawkes really represents is killing people in the name of the Pope. Anarchists don't seem to follow the same ideology, so why use him?
