A defiant declaration of atheism by an Indonesian civil servant has inflamed passions in the worlds most populous Muslim nation, pitting non-believers and believers against each other.
The trouble began when civil servant Alexander Aan posted a message on the Facebook page of Atheist Minang, a group of Indonesians with godless beliefs. It read: God doesnt exist.
The post so enraged residents in Aans hometown of Pulau Punjung in West Sumatra province that an angry mob of dozens stormed his office and beat up the 30-year-old.
To add insult to injury, police then arrested him and now want to press blasphemy charges that could see him locked up for five years.
Muslim extremists have called for Aan to be beheaded but fellow atheists have rallied round, and urged him to stand by his convictions despite the pressure.
Dear Alex, stick to your beliefs. This country has no right to restrict your faith, Fahd Singa Diwirja wrote on the same Facebook page, where Aan is one of the administrators.
Youre facing narrow-minded people, but this is the true Indonesia, a fertile ground for the spread of fundamentalism, Diwirja added, advising Aan to escape persecution by seeking asylum in a European country.
Aan has also gained the support of the US-based International Atheist Alliance.
The group, together with Atheist Minang, has written to President Susilo Bambang Yudhoyono, calling on him to ensure that the blasphemy allegations are dropped.
This is a law that has been used to promote mob violence and intimidation against those who do not agree with ... vigilante groups, said the letter, copies of which were also sent to the United Nations and Human Rights Watch.
Aans proclamation has been removed from the page, but the Facebook group has doubled to 2,000 since the controversy made local news reports.
Most of the postings, however, are diatribes against Aan and his supporters.
These atheists should be beheaded, thats what they deserve, wrote a man who identified himself as Putra Tama, a Muslim from neighboring Jambi province.
Other posts challenged atheists from the group to dare show themselves, instead of hiding behind the anonymity of social media.
If you think your arguments are true, why dont you just have a face-to-face meeting with us, people who still believe in God? Youre just a group of cowards, taunted a post by another Muslim.
Although Indonesias constitution guarantees freedom of religion, it only recognizes six faiths: Islam, Buddhism, Hinduism, Catholicism, Protestantism and Confucianism.
Perceived blasphemy against any one of these religions carries a maximum five-year jail term.
