A demand letter to history, written by people who refuse to ask politely.
means A public written declaration of the aims, beliefs, and intentions of a person, group, or movement.
from From Italian 'manifesto,' meaning 'a public declaration,' which traces back to the Latin 'manifestus' — 'plain, clear, evident,' literally 'struck by the hand,' from 'manus' (hand) plus a root related to '-festus' (struck). The image is of something so obvious it could be grasped by hand or laid open in the open palm. It entered English in the 17th century, and by the time Marx and Engels published theirs, the word had fully absorbed its modern flavor: not just a statement, but a statement that dares you to disagree.
