This amendment states that the right to freedom of speech, religion, press, and assembly is open to all. The government cannot prohibit someone from these actions because it would be infringing upon their Constitutional rights.
This segment from the Colbert Report pokes fun at closed-minded individuals. The host uses the example of a Muslim girl being told to modify her religious head cover because of her job to show that some people do not accept other beliefs. While humorous, the excerpt demonstrates how small minded individuals can be. This applies to the first amendment because freedom of religion is guaranteed under the Bill of Rights.
