Exactly...your saying our opinion is based on our loyalties...ie what side we are on, not actual empirical data. This just leads to close mindedness and extermism on both sides.
You say bin laden did *nothing* good.....but what do you actually know of what he did apart from what your side is telling you. He was supposedly a very quiet, humble man, intelligent and well educated and I'm sure he did a lot of good for "his people" - which just as the good you see our leaders do, would balance out the bad Bin Laden did in his peoples opinion.
There are just as many people in the world who dont think he was an evil terrorist, but a freedom fighter and who do think Bush/Blair are the terrorists. So, their opinion is wrong and ours is right just because of "sides" ?
There is no absolute right or wrong - generally might is right. It was a war (on both sides) and we killed him before he killed "us"...we won this part of the battle, thats all - I dont see any moral high ground being won.
Martin McGuinness was an "evil terrorist" who murdered people, now he is part of the ruling elite *shrug*
Its easy to use pejorative statements to mould peoples opinions to how we want them to think only to change them when it suits our aims.
