It is often argued that the main problem with atheists is their lack of moral guidelines. This is because society in general is currently not used to individuals taking responsibility for their own actions and guidelines, and instead assumes that we all need to be governed by a higher authority. Atheisms break this typical mould because they rely on rationality and reason for their morality. Usually, Atheists will come to similar conclusions about morality when it comes to the value of life and freedom of thought. However, these conclusions often conflict with the beliefs of religious people.
If atheists were a strongly defined group that could adopt a strongly defined, albeit secular, set of morals, perhaps more religious people could be persuaded to drop their supernatural beliefs. Many religious people often question the validity of their beliefs and science continues to strip their credibility, but very few doubt the morals that religion gives them. This is what gives religion its strength.
However, atheism is not a strongly defined group, and therefore can never adopt its own strongly defined set of morals with which to "advertise" itself. This is one reason religious fundamentalists feel so strongly about infidels. Atheists are anarchists, they say. They have no rules for how to live their life.
Many atheists will just look at this statement with contempt, agreeing that they enjoy debauching and sinning, but in reality most atheists will disagree that their lives are lacking any moral guidelines. To go further, some atheists will argue that their moral guidelines are better than that of a religious person. That is because an atheist's morals are derived from reality.
Atheists have no make-believe god or child-molesting priest telling them what is right and wrong. Their minds are not corrupted by guilt or false promises. Eventually atheists will come to the conclusion that harming other people or their property is bad, whereas making people happy and helping others is good. Sound a little similar to religion's moral guidelines? Well it is. With one major difference.
This difference between the morals of religion and atheism is that religion JUDGES first.
Religious people believe so absolutely in the moral guidelines penned by corrupt leaders thousands of years ago in dark and perverted times, that they are therefore better than atheists. But as I've just explained, atheists have many of the same morals. It's just that religious people take it upon themselves to decide who to apply these morals to. If you're a homosexual, or even someone who doesn't believe the same as them, this morality does not apply to you. It is ok to harm you, physically, or by means of taking away your rights. This is where the problems occur.
Atheists tend not to judge. They are more accepting of people with different beliefs. They have no demented certainty to force onto others. The morality is still based on not harming others, and being a good human being. Unlike religious people, they don't reserve this morality for people with the same beliefs.
