"Today is September 30th, also known as Blasphemy Rights day."

"This day is dedicated to those who are systematically being persecuted, harassed, or killed for their simple expression of Freethought (more precisely, for their �blasphemous� views towards religion)."

If being religious is someone�s right, then being critical to religion is also one�s right. There is nothing wrong to be critical to any idea or ideology, as CFI aptly put on its Blasphemy day banner � �Ideas do not need rights, People do�!

Afterward, an Islamist group "Ansar Bangla-7" reportedly tweeted, "Target Down here in Bangladesh."
