The director of a school in Tallahassee, Florida, was forced to resign after parents complained about her art history classes, claiming that Michelangelo's sculpture of David - one of the most famous sculptures in the world - is pornographic, writes The Daily Mail.

Hope Karaskila was forced out of Tallahassee Classical School because three parents complained about the curriculum.

Two parents said they were unaware their children would be shown images of the sculpture, while a third parent called the world's most famous statue "pornography"..

They also said that the pictures "they upset their children a lot".

Principal Caraskilla told the Tallahassee Democrat that she was deeply saddened that her short tenure at the school ended so abruptly. Namely, Karaskila was appointed to that position only one year before.

The incident represents another point of contention in the increasingly heated debate over curriculum in American schools. On the one hand, public schools in Democratic cities have come under fire for pushing liberal curricula and programs without parental consent and advocating progressive policy changes when it comes to transgender children.

In the case of the Tallahassee Classical School, several apparently easily offended parents forced the resignation of the experienced principal.

The sculpture of David was among the artworks being studied in a Renaissance art class for Year 11 and 12 students.

The masterpiece was created between 1501 and 1504 and is considered the most significant sculpture in the world.

But the Tallahassee parents considered the act inappropriate because David is – naked.

They now require that any topics or lessons that might be considered "controversial" be put to a vote in advance.

"Parental rights come first, and that means protecting the interests of all parents, whether there's one, 10, 20 or 50," said school board president Barney Bishop.

He admitted that he gave Karaskyla an ultimatum, telling her that either she had to resign or be fired.
