The declaration of independence refers to rights as being unalienable. what does “unalienable” mean?

Unalienable, most commonly seen as "inalienable," means that something cannot be violated or taken away. It also means that it cannot be given away by the possessor. The word is used in the Declaration of Independence to convey the idea of rights as being inherent to the fact of being human. Therefore, no law or government could take them away. It protected every American, including future generations.

would it be plagiarism to copy and paste off of here? ?

chavez's example shows that nonviolent protest can work well. it shows that one nonviolent man can stop a mob, which proves chavez's point and persuades people to protest nonviolently.
