Every now and then Nahida (The Fatal Feminist) totally nails it:
Most people, especially most religious people, are not aware that they are not living in a vacuum. They aren’t aware that their words and actions are politically charged, or of the wider implications and interpretational consequences. They think they are just being religious. They think they are just being religious and living their lives even when they are involving this in politics.
Replace “Muslim” with “Christian” and “Qur’an” or “shari’ah law” with “Bible”, and the post still works on nearly every level.
