So you condone the use of church-sanctioned torture and execution to silence religious dissenters? Now that's a scary thought.
My two cents on
god - Why should god even exist? The Greeks believed in Zeus and the rest of the gang on Mt Olympus. The Aztecs believed in Tezcatlipoca and Quetzalcoatl. And yet, in this day and age, they're nothing more than an amusing anecdote in history textbooks. Why should this god (or Allah, Buddha, whatever) be any different than Athena or Thor? Religion is a fad; people believe in a god until he/she/it becomes unpopular or irrelevant and is replaced by another all-powerful incarnation.
religion - Religion does more harm than good. As mentioned before, religion often directly contributes to the cause of wars, violent conflicts, torture and death. Examples include the Crusades, the Salem Witch Hunt, enslavement of Africans, the KKK, the IRA's conflict with the British, and the events of September 11th. Coupled with the recent unveiling of pedophilic preists, I have to say that while religion often has good intentions, it is ultimately the cause for more pain and unrest.
Well, back then. People were stupid, they needed something to look to. The only people who were educated were priests.
