Religion and science have had many confrontations in the past 500 years. An example of this would be the dispute between evolution and creationism. Many christian religions have a strong belief in creationism, but science has proven again and again that there is evidence of evolution. Because of this dispute in some parts of the United States it is unethical to teach evolution in schools. There are also underlying disputes between popular culture and religion.
Popular culture seems to encourage premarital sex, but most religions find it to be immoral.
Another dispute or disagreement is the impact of religion in government. In some countries, such as the US, there is a separation between government and religion. In other countries, such as Iran, the government is based on religion. This disagreement is based upon society as a whole and the contributing beliefs of that society. This example can also be easily tied to the disagreement between religion and popular culture.
