PRAGUE, 4 February 2006 (RFE/RL) -- The row over the Muhammad cartoons had been brewing for weeks.
But it was the armed raid on a European Union office in Gaza on 30 January that spurred Belgian Tijl Vercaemer to act.
"I got the idea on Monday after the raid and I wanted to do something positive, nothing provocative, but some positive action," he says. "So I created the website and registered the domain name supportDenmark.com and on Tuesday the website was online."
SupportDenmark.com urges people to do just that -- by buying Danish products, or by posting Internet pictures of the Danish flag with the message "I support Denmark in its struggle for freedom of speech."
Vercaemer says he has received thousands of emails from around the world, most of them supportive.
"It's mostly about freedom of expression and also people want to buy Danish goods," he says, "but it's just that they are shocked at how it's possible that the Muslim world can demand of us what we should or should not publish in our newspapers."
Vercaemer's website is part of an emerging, predominantly online, response to the campaign to boycott Danish goods.
The idea for a "Buy Danish" campaign has also appeared in conversations posted on blogs such as littlegreenfootballs.com, or the History News Network, a website at the George Mason University in the United States.
It published a list of Danish goods like cheese, beer, and porcelain, as well as online stores that stock them. A Belgian news and opinion website (Brusselsjournal.com), meanwhile, proclaims on its front page, "We are all Danes now!"
There is also an online petition (petitiononline.com/danmark/petition.html) that says it has more than 5,500 signatures in support of "Jyllands-Posten," the newspaper that originally printed the cartoons.
Some of the online campaigners say they understand how a cartoon showing the Prophet Muhammad with a bomb-shaped turban can offend Muslims.
But they say freedom of speech includes the right to be offensive.
Eric Mortensen is the man behind Advar.org, a Norwegian website urging readers to "Buy Danish."
The world "advar" means "warn," and it is also the Norwegian acronym for "campaign for Danish goods."
"There was also a Norwegian paper that printed these cartoons and that's when it became a big issue in Norway," Mortensen says. "We felt the Norwegian government wasn't supportive enough of free speech and they were almost apologizing for this paper's right to print these cartoons."
Some of the sites in support of Denmark have anti-Muslim or anti-immigrant overtones. But Mortensen says his has no political agenda.
"No, we are definitely not anti-immigration, we are pro-immigration," he says. "This is nothing to do with Islam, nothing to do with immigration, this has to do with protecting freedom of speech and secular democracy."
The boycott of Danish goods across the Middle East could deal a real financial blow to Danish exporters. Danish dairy foods have already disappeared from many supermarkets and at least one company -- Arla -- has announced job cuts.
The people behind the "anti-boycott boycott" acknowledge their supporters are unlikely to fill that financial hole by eating Danish cheese.
They say their goal is more modest -- to give Denmark moral, if not financial, support.
