principle that debate on public issues should be uninhibited, robust, and wide-open.” New York Times Co. v. Sullivan, 376 U. S. 254, 270 (1964). That is because “speech concerning public affairs is more than self-expression; it is the essence of self-government.” Garrison v. Louisiana, 379 U. S. 64, 74–75 (1964).
