This is offensive why? Do you object to medical science in general? This is an educational exhibit not a halloween show. Some people may be squeamish about it. Those people shouldn’t attend.
As someone who works in the Bodywork and therapy business, I have no problem with this at all. When I was in school I studied with books of photographs of dissected bodies, used real human skeltons in the classroom, and even attended a dissection. Am I a pervert?
Exhibits like this could certainly inspire some young people to go into the medical field as well as educating adults about their bodies.
