The Third Amendment is the most outdated amendment in the Bill of Rights. This amendment protects the citizens of the United States from soldiers being quartered in their house without their permission. This amendment was in response to people in the colonies being forced to house British soldiers against their will. I like most people would be more than welcome to let any American Soldier stay at my house in time of need. So I doubt that this amendment will have any challenges to it in the future.
This picture to me makes fun of the outdated Third Amendment. I doubt anybody would want to be forced to house a soldier if they did not want to, but if they did repeal the Third Amendment I doubt it would affect society today at all. Most people I think like me would house a soldier in a time of need without being forced.
This video shows one of the main reasons why the Third Amendment is outdated, American military personnel are provided housing. Most likely the only reason a soldier would ever have to stay at a citizens house would be in time of war, and the Third Amendment doesn't protect against quartering in time of war (however it would be regulated by law).
