Just a few quotes I have come across over the years of exploring freethinking/atheism material on the web. Some of them help to wrap up effective points into small packages.
"If you talk to God, you are praying. If God talks to you, you have schizophrenia.
~ Thomas Szasz
"Could a being create the fifty billion galaxies, each with two hundred billion stars, then rejoice in the smell of burning goat flesh?
~ Ron Patterson
"I am convinced that I am acting as the agent of our Creator. By fighting off the Jews, I am doing the Lord’s work.
~ Adolf Hitler (just to debunk the myth of Hitler being an atheist)
"To use the term blind faith, is to use an adjective needlessly.
~ Julian Ruck
"When did I realize I was God? Well, I was praying and I suddenly realized I was talking to myself."
~ Jack Gurney – “The Ruling Class”
“...if the definition of God is unfalsifiable, the question of the existence of God is meaningless.”
"We must question the story logic of having an all-knowing all-powerful God, who creates faulty Humans, and then blames them for his own mistakes."
~ Gene Roddenberry
