Given the set of tradeoffs described in the article, I'm on record supporting free speech, period. As I wrote earlier here on HN, "The basic issue is whether people in free countries, like most readers of Hacker News, are going to be able to enjoy the right of free speech throughout their country, on any subject, or whether any American or Dutch or Danish person or other person accustomed to free speech who happens to be within reach of attack by a crazy foreign person has to prepare for war just to continue to exercise free speech. On my part, I'm going to continue to comment on public policy based on verifiable facts and reason and logic, even if that seems offensive. I am not going to shrink from saying that people in backward, poorly governed countries that could never have invented the Internet have no right to kill and destroy just because someone in a free country laughs or scorns at their delusions. The people who are destroying diplomatic buildings and killing diplomats are declining to use thoughtful discussion to show that they are anything other than blights on humankind.
"Allow me to reemphasize this point. The many participants on HN who criticize Transportation Security Agency 'security theater' as a meaningless reduction in the freedom of people who travel to the United States are right on the basic point. If free citizens of free countries can't live in freedom because of fear of terrorists, the terrorists have already won. You and I should be able to speak our minds and express our opinions in the manner of all people in free countries--sometimes agreeing with one another, sometimes disagreeing, but always letting the other guy have his say. To engage in self-censorship because of fear of violent thugs is to be defeated by the thugs."
As before, I think jerf correctly responded to this issue when he made his comment on it last month:

If I organize a riot involving thousands of people that I manage to incite into killing people, and I claim my reason is that I heard that some guy is Glasgow made fun of the American soccer team over beer... that guy is Glasgow is not the real reason. It doesn't even qualify as a metaphorical fig leaf, it's just a lie. When the excuse is this tiny, you shouldn't even give it the time of day.
I have to agree with the submitted article that the correct policy is making sure to protect the right of free people in free countries to speak freely about all the issues of the day, including the harm caused to the whole world by fanatics who burn and destroy and kill because their delusional beliefs are offended.
