Blasphemy Day – September 30, 2025

Would you want to live in a world where your thoughts and speech are punishable by death? Well, this very grim prospect is the reality of millions of people living in countries with blasphemy laws. Blasphemy refers to speech that insults or disagrees with a religion and its teachings. Since 2009, September 30 is marked by the Center of Inquiry as International Blasphemy Rights Day to raise awareness for the cruel blasphemy laws practiced in over 69 countries.

History of Blasphemy Day

On 30 September 2005, a Danish newspaper named “Jyllands-Posten” posted 12 editorial cartoons of Muhammad, the founder of Islam. The move, justified by the newspaper as an attempt to criticize Islamic censorship, angered prominent Danish-Muslim groups. After a failed court case and lack of support from the government, a congregation of Danish imams, led by Ahmed Akkari visited the Middle East to drum up support for the cause.

After months of hysteria and manufactured lies, Ahmed Akkari sought enough support from Muslim-majority nations to launch a movement against the Danish government. The protests reached far and wide and had major international implications. Danish embassies around the world were bombed and over 100 people, including the protestors, were killed.

This stunning act of religious intolerance shook the world and triggered many debates about freedom of speech. Years after the matter settled down, Ronald A. Lindsay, CEO of the Center for Inquiry, was presented with the idea of honoring the right to free speech on the anniversary of the Danish article. The idea was accepted and since 2009, every September 30 is celebrated as International Blasphemy Rights Day.

It is important to clear the air on the intent of this day. International Blasphemy Rights Day is observed in defense of free speech, not in support of ridiculing a particular religious belief. Blasphemy laws violate the tenets of our collective freedom. International Blasphemy Rights Day is observed in reaffirmation of our belief that no religion or sect is beyond criticism.

Why We Observe Blasphemy Day

  1. Injustice anywhere is a threat to justice everywhere

    Reiterating the words of the great Martin Luther King Jr., human beings everywhere are “tied in a single garment of destiny.” Turning our heads away from the grave injustices that others face can be catastrophic. It is our moral imperative to raise our voices against the injustices happening thousands of miles away from us.

  2. Blasphemy laws deserve global condemnation

    It is our shared belief that no religion is beyond criticism. The freedom to voice our opinions against discrimination and injustice cannot be threatened. Yet, this is the reality of millions of people. By coming together on September 30, we send an astounding rejection to the enablers of blasphemy laws everywhere.

  3. Change is possible

    Resistance to oppressive policies is never futile. There has been a tremendous social change in the last decade alone. We believe we will one day see a future free of blasphemy laws, and that is why we observe International Blasphemy Rights Day.
