Here is what atheists are up against:

In the occasion of the national holiday St. Bededag (Great Praying Day) here in Denmark, I’m bringing you a stack of anti-religious quotations that may – or may not – stimulate your mind.
Roman philosopher Seneca the Younger:
“Religion is regarded by the common people as true, by the wise as false, and by the rulers as useful.“
French military and political leader Napoleon:
“Religion is excellent stuff for keeping common people quiet.“
German philosopher Karl Marx:
“Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.“
Jewish German-born physicist Albert Einstein:
“A man’s ethical behavior should be based effectually on sympathy, education, and social ties; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.“
English philosopher Bertrand Russell:
“The objections to religion are of two sorts – intellectual and moral. The intellectual objection is that there is no reason to suppose any religion true; the moral objection is that religious precepts date from a time when men were more cruel than they are and therefore tend to perpetuate inhumanities which the moral conscience of the age would otherwise outgrow.“
American novelist Ernest Hemingway:
“All thinking men are atheists.“
British-American actor Charles Chaplin:
“By simple common sense I don’t believe in God, in none.”
English biologist Richard Dawkins:
“I am against religion because it teaches us to be satisfied with not understanding the world.“
