According to a Defense Department approved "sexism course," the Bible, the U.S. Constitution and the Declaration of Independence all contribute to modern sexism.

Those three cherished texts all count as "historical influences that allow sexism to continue," according to a presentation prepared by the Defense Equal Opportunity Management Institute, whose mission is to give a "world-class human relations education."

According to the course, the Bible has "quotes" which can be interpreted as sexist by readers.

The Declaration of Independence is also an historical cause of sexism, as the document refers only to "all men" —not "men and women."

And the Constitution, the Pentagon argues, is an historical source of sexism because "slaves and women were not included until later in history."

Of course, members of the Armed Forces take an oath to defend the Constitution — which is, according to the DEOMI course, an "historical influence that allows sexism to continue."

"The content of the lesson is provided to generate academic discussion concerning how these historical documents have been included in discussions about the topic of sexism," Lt. Cmdr. Nate Christensen, a Defense Department spokesman, told The Daily Caller.

But following TheDC's request for comment, the sexism course — as well as two other courses listed on DEOMI's website, entitled "Prejudice & Discrimination" and "Racism" — were taken offline.

"This course is currently offline and under revision," a notice says under all three courses.
