Charles Murray was shouted down and physically assaulted after at Middlebury for Bell Curve views. Protesters surrounded car, shoved moderator Allison Stanger, yanked her hair requiring neck brace. Bell Curve claims intelligence largely genetic with major racial differences. Blacks and Latinos suffer genetic inferiority causing inequality per SPLC summary of Murray. Students and faculty justify silencing as admins routinely exclude bad ideas from campus slots. Shouting down equals admin silencing for harmful or discredited content. Murray's racial IQ views deemed pseudoscience justifying no-platforming. Defenders analogize to removing disruptive preachers to protect students. Silencing advances moral ends like preventing dehumanization of minorities. Faculty wield silencing power substantively not just by authority. Students claim same right to block racist ideas as settled wrong. No-platforming targets views like racial intellectual differences as toxic. Protesters reject institutional speech frames as oppressive. Violence justified if structural inequality demands it per some. Free speech absolutism ignores admin precedents for exclusion.
