HUD Assistant Secretary for Fair Housing Roberta Achtenberg has been quoted as saying "HUD walks a tightrope between free speech and fair housing. We are ever mindful of the need to maintain the proper balance between these rights." Libertarian critic James Bovard commented that, "The more aggressive HUD becomes, the fewer free speech rights Americans have. Many words and phrases are now effectively forbidden in real estate ads... Apparently, there are two separate versions of the Bill of Rights -- one for private citizens and the other for federal bureaucrats and politicians".
