Political Rhetoric (Extremism), 1974
The use of intimidation, sabotage, or violence to prevent a person from being heard by others. Always justified morally against anyone not fully persuaded of extremist left-wing ideas.
“No-Platform” was a form of “direct action” (“prior restraint”) devised in 1974 by the International Marxist Group (IMG) and International Socialists (IS) as an extreme tactic against the hard-right National Front’s recruitment activities on university campuses, and was formally adopted by the National Union of Students (NUS). It was so extreme, even the most left-wing newspapers denounced it.
