Unalienable Rights and Government by Consent
Unalienable rights are rights that cannot be taken away. Some examples are the freedom of speech, religion, etc. A government by consent means that the people have a voice in the government and can also be elected into office. A government needs consent of the governed or else there will be a sense of tyranny and it won't be fair for the people if they can't express their ideas about the government.
The government is responsible for protecting and guaranteeing our unalienable rights. The unalienable rights and consent of the governed are not outdated because they represent basic ideas that will always be needed. These principles matter to me because these things are what keeps us safe. Without consent of the governed, there would be tyranny and things would be a lot different. Without unalienable rights, we wouldn't have the freedom of speech, religion, etc. Here is some more information I found on unalienable rights.
