If you don't agree with their lifestyle, or tell lies about a political leader, you did not vote for.

The full faith and credit clause in the Constitution addresses the recognition and enforcement of legal documents and judgments across state lines. It generally ensures that states must honor the public acts, records, and judicial proceedings of other states.

Based on the information provided, the only action that citizens can legally do because of the full faith and credit clause is drive a car in one state with a driver's license from another state. This is because the clause ensures that states must recognize valid driver's licenses issued by other states.

The other actions mentioned, such as paying income taxes in a different state with lower taxes, refusing to serve people based on their lifestyle, or spreading false information about a political leader, are not directly related to the full faith and credit clause. These actions may involve other Constitutional principles, laws, or regulations.
