The BBC reports on the murder of Avijit Roy and what it means for Bangladesh and other dissenters.
Hundreds of people gathered in Dhaka to mourn the blogger’s death.
Mr Roy’s family say he received threats after publishing articles promoting secular views, science and social issues on his Bengali-language blog, Mukto-mona (Free Mind).
He defended atheism in a recent Facebook post, calling it a “rational concept to oppose any unscientific and irrational belief”.
His Mukto-mona website on Friday bore the message in Bengali “we are grieving but we shall overcome” against a black background.
Like Charlie Hebdo last month.
In a forthcoming article to be published in the Free Inquiry magazine of April-May 2015, Mr Roy likens religious extremism to a “highly contagious virus”.
I have a column in that issue. What’s it about? Charlie Hebdo and Raif Badawi, and the nature of the Saudi regime. It’s almost as if there’s only one subject these days.
Death threats against atheist writers and bloggers are nothing new in Bangladesh.
Prominent writer Taslima Nasreen had to leave Bangladesh after she received death threats from hard-line Islamists in the mid-1990s.
She wrote on her blog: “Avijit Roy has been killed the way other free thinker writers were killed in Bangladesh. No free thinker is safe in Bangladesh.
“Islamic terrorists can do whatever they like. They can kill people with no qualms whatsoever.”
That’s what god-obsession gets you.
