Forgive me if I fail to get teary-eyed and inspired by the grassroots boycott organized by international credit corporations - or the fact that these global conglomerates didn't express the same righteous anger over things like racism, genocides, and terrorism as they have over a guy running a website where he reveals things that you're not supposed to mention.
Edit: Jack99 - the KKK got famous by LYNCHING people. I'm fairly certain that at least a few states have criminalized murder.
Edit: I should add to the people talking about "breaking US law" and "illegal" that, while many US lawmakers are racing to try to pass laws illegalizing what WikiLeaks is doing, it's not actually illegal YET, on account of a few pesky things like the freedom of information, and the insistence of a few "founding father" types who thought that citizens ought to be entitled to know what their government is doing.
While many lawmakers, apparently egged on by many citizens, are frantically trying to enshrine the government's right to conceal what it's doing from the citizens who elected it to represent them, they're scratching their heads as to why no one's ever done it before. While, for instance, a military commanding officer can tell you that a certain document is for another military officer's eyes only, or a government can throw a foreign spy in jail for trying to spread such documents, a citizen who sees the government doing something horrible is still currently perfectly free to say, "hey, look everybody: look what they're doing. It isn't right!" And, currently, that's the non-crime WikiLeaks is involved in - which is why Sweden is trying to extradite the owner on years-old sex crime allegations, and why the US is trying to pass laws really quick that we can use against him.
