WTF... Seriously. The IRA (Well all the different factions thereof) is a criminal organisation that has *killed* thousands of people. (Or is this some pacifist Swedish I.R.A. that I'm not aware of?)
The Pirate Bay has caused no loss of life with its intellectual property infringement. Unless you count the despairing MPAA executives jumping to their deaths. That prosecutor has no fscking idea what he is talking about. Seriously.
It's basically the same as comparing Bush, Blair, [insert disliked politician] to Adolf Hitler, or calling certain groups Nazis (that don't actually have an anti-foreigner agenda). Totally asinine and downright dangerous in any case, except when the groups involved are *actually* Neo-Nazis of some shape or form.
Stupid comparisons like this cause people to forget how horrific some things were, and cheapens the lessons that history has taught us at so great a cost.
[Disclaimer: I'm Irish, so this is a particular gripe of mine.]
