Atheists and freethinkers have a visible presence in the United States. Many encounter them first through seeing a Darwin's Fish bumper sticker on a car.
First came the fish bumper stickers, imported from the United States and pasted on cars by members of Egypt's Coptic minority as a symbol of their Christianity. Before long, some Muslims responded with their own bumper stickers: fish-hungry sharks. The stickers are sold in Islamic bookshops and some also come plain or fancy – some with the Arabic phrase "No god but Allah" printed in the shark's body. Emad, a Muslim, laughed when asked about the competing symbols but was unapologetic about the two shark stickers on his car. "The Christians had the fish so we responded with the shark. If they want to portray themselves as weak fishes, OK. We are the strongest," said Emad who would only give his first name.
