Some people believe that government exists to promote one religion or culture over another, because they want the historically prevailing culture and religion to always remain the same. Libertarians reject this idea, and believe that government should not discriminate based on gender, race, ethnicity, religion, or for any other reason. All citizens must be treated equally by government, and governments exist to protect the right of all religions and cultures to freely speak and attempt to gain converts using the art of persuasion. Government should only intervene in human relationships to protect against force or fraud, or to punish those who commit these actions.
