The subject that deals with issues like these is philosophy. The creators of this site supports Objectivism, the philosophy of Ayn Rand . Objectivism , therefore, claims that respect for individual rights is the only moral basis on which to organise a society. In this kind of society the only functions of government is the police, the military and the courts. The two most important forces that fight against these ideas today are religion and environmentalism.
Religion is therefore a destroyer of man's happiness.
