Yet another pro-life speaker faced hostility on a college campus recently when she explained why babies in the womb deserve a right to life.

Star Parker, a strong advocate for life in the black community, recently spoke at the California State University Los Angeles at the request of the Young Americans for Freedom student chapter. Parker had four abortions early in her life. She said she used abortion as a method of birth control because she got “caught up in the lies of the Left.” Now, she works as the founder and president of the Center for Urban Renewal and Education , a public policy organization that promotes market-based solutions to fight poverty. She also is a sought-after pro-life speaker.

But at California State, Parker’s comparison of abortion to slavery angered psychology professor Dr. Heidi Riggio. During a question and answer period, Riggio publicly berated Parker and then stormed out of the room, according to Campus Reform.

Here’s more from the report:

Video footage of the altercation captured by YAF shows Riggio asking Parker to address “the link between the legality of abortion and safety” during a Q&A session at the end of the event, challenging Parker with the claim that the incidence of abortion is unrelated to its legality, and that illegal abortions present much greater health risks. Parker attempted to respond by arguing that “in a civil society, abortion should be illegal,” but Riggio admonished her, saying, “you want to impose your religion on everybody.” Click here to sign up for pro-life news alerts from LifeNews.com When Parker retorted by asking whether Riggio would consider slavery a “religious question,” Riggio indignantly replied that “I’m not talking about slavery,” repeating the mantra several times while Parker continued to highlight parallels between the decisions in Roe v. Wade and Dred Scott. After a nearly four-minute dialogue, Parker bemusedly observes that, in the end, “one of us is going to win,” prompting Riggio to shrilly predict that “it’s not going to be you” as she stormed out of the venue.

Students who attended the event told Campus Reform that Riggio’s behavior toward the guest speaker was “totally unprofessional” and childish.

This type of hostility is not rare on college campuses. In 2012, the Alliance Defense Fund filed a lawsuit against Texas A&M University on behalf of a student club after administrators blocked it from bringing Parker on campus to speak to students. College officials told the group that its request could not “be approved for recognized organizations with a classification of social and political issues.”

Earlier this month, college administrators told the DePaul University College Republicans that they could not hang up a poster with the words “Unborn Lives Matter” on campus because the language might “provoke” other students.

The DePaul University College Republicans created the simple black and white poster to advertise their club meetings and recently submitted it to administrators for approval, according to the Daily Wire.

The poster design was passed all the way up to university President Rev. Dennis H. Holtschneider who rejected it for being too similar to “Black Lives Matter” and linked the pro-life message to “bigotry that occurs under the cover of free speech.”
