Censorship =/= dignity, ethics, morals, decency standards, and least of all "fairness" (ahem). It just becomes more bureaucracy on top of itself when you do censor free speech.
Denying that something actually happened that actually did is foolish, I agree.
Sackable offense?...Perhaps only when it (said sentiment of free speech per entity) crosses over into treason or it is somehow subversive.
Simply denying it? No...just deserves ridicule.
