Journalists as censors

For whatever reason journalism groups are jumping on the bandwagon of inhibiting speech or using doublespeak to fit their agendas. NAHJ calls for the use of "undocumented workers" instead of "illegal immigrants"; the NABJ calling for the firing of vile Don Imus; and now the NAAJ asking journalists to not identify the ethnicity of the Virginia Tech killer.
It's amazing that organizations that should be using everything, including the kitchen sink, to protect freedom of speech and to fight against censorship, either within or outside the newsroom, are so quick to do the exact opposite.
UPDATE: NAAJ responds to criticism.
