Suicide bombings aren't generally linked to religion, they're linked to people fighting against democracies which are occupying their homeland. Muslims don't own the market on terrorism, in fact one of the most lethal acts of terrorism in the 20th century (the King David Hotel bombing) was perpetrated by Israelis. The reason? They wanted the British to stop occupying their homeland. Sound familiar? Other examples include Sri Lanka (suicide bombings by atheist/marxist Tamil Tigers) and even Hezbollah suicide bombers, which were 8% christian (According to the book "Dying to Win: The Strategic Logic of Suicide Terrorism"). It just so happens that a lot of Muslim areas are under occupation, so they're all getting painted with the same broad brush. Trust me, if the US were occupied by a bunch of wealthy muslims, you'd see Southern Baptists strapping on explosive belts eventually. Religion is only circumstantially linked.
