Some seniors at the University of Notre Dame say they will skip their upcoming graduation ceremony because President Barack Obama is scheduled to deliver the commencement speech.

They, and other pro-life Catholics, are angry at the university for allowing the pro-choice president to speak, and for awarding him an honorary degree.

"It's not a political issue. This is an issue of human dignity and it's a Catholic issue and it's an issue of science and as a Catholic university we need to stand up for it," one senior said in a YouTube vide.

"And while there may be a diversity of opinion and academic debate, that is something that is welcome, but not to the extent that it replaces the foundation of who we are," another continued.

"Bestowing an honor on him is equal to bestowing an honor to those policies which are in contradiction to Catholic teachings," a third student said.

The student-produced video is being seen across the Internet.

The seniors skipping graduation will gather with hundreds of others for a campus prayer vigil during Sunday's graduation.

Notre Dame's president says having President Obama speak does not mean the school universally supports his policies.
