“”The pen is mightier than the sword”
“The pen is mightier than the sword” is a metonymic adage, penned by English author Edward Bulwer-Lytton in 1839, indicating that communication, or in some interpretations, administrative power or advocacy of an independent press, is a more effective tool than direct violence.”
Parler should NOT chill free speech including rhetorical hyperbole.
