Examples of taxidermied humans are really quite rare.  Far too often other forms of preservation, such as mummification and embalming (Lenin and Evita Peron come immediately to mind) are indiscriminately lumped under the heading of "taxidermy".

The General Public's current moral viewpoint of bodies on display is that  if they are taxidermied, it's "offensive".   As with taxidermied pets, I suspect that the association of Taxidermy as Trophy has something to do with this knee-jerk reaction of righteous indignation.

On the "acceptable" list are bodies that are embalmed (or not) in open casket displays, Bog People, Egyptian mummies and all sorts of bits of saints. 

Becoming very popular, and therefore acceptable, are bodies preserved by plastination (Gunther von Hagens).  This is in part due to the display venue being changed from art museums to science museums.  (They also have very little remaining skin.)

The context of display certainly has it's moral politics and science museums are by no means exempt from public scrutiny.  The few known remaining examples of humans preserved thorough the taxidermy process are hidden away from public view and outcry.  If displayed they run the risk of being targeted by outspoken morality minders and destroyed.
