I don't know much about chiropractice, but my gut feeling is to kind of agree with the profs on this. However, my gut feeling also tells me that chiropractice(y?) is lots less harmful than the socialist and PC venom that most universities teach today.
The little satirical map could show a school of socialism, only it would hardly be satire.
The worst thing, I suppose, would be a cultural Marxist professor of sociology with no medical training presuming to perform procedures on one's spine. Double whammy.
