French Resistance to Nazis and the IRA

I sometimes saw people expressing the opinion that if the IRA are "terrorists", so were the French Resistance against the Nazis.

I also came across a post titled: My grandfather was an IRA terrorist (and comments after it).

Another pro Irish poster writes:"My grandparents were in Ulster during the Black and Tan war andsuffered Orange pogroms before that so this all is not such unexpectedbehavior from the English. They should stop whining about LordMountbatten and the Grand Hotel and Canary Wharf and mortars fired at10 Downing Street - if they want their problems with Ireland over withthey should just pack up and go back to their own god-damned country."
