Oh sure. Of course. See a photo of people sending a message of solidarity to imprisoned atheists in majority-Muslim countries, a photo organized by Maryam Namazie, the founder of the Council of Ex-Muslims of Britain and inspiration for Councils of Ex-Muslims elsewhere such as Morocco, France, North America.
In that photo we’re all holding messages we composed for the purpose. Mine said “WE ARE ATHEIST. WE ARE WITH YOU.”
See that, I say, and photoshop it for a rather different purpose.
That’s atheist solidarity for you. I’m sure the persecuted atheists in majority-Muslim countries are very grateful.
