A battle is heating up at Kauffman Stadium but it's not about baseball, it's about abortion.
Right now, the Royals run commercials for the Vitae group on the radio and at Kauffman Stadium.
On Tuesday, at Kauffman Stadium UltraViolet hired a messaging plane to fly over the stadium with the words, "ROYALS FANS DESERVE THE TRUTH — DROP VITAE".
Last week, UltraViolet launched a petition drive .
Its leaders said more than 40,000 people have signed the petition asking the Royals to end its relationship with the Vitae Foundation
"This partnership is part of a deceptive anti-choice agenda. The Kansas City Royals are not only condoning it but they are willingly participating edit and amplifying it," said Karin Roland, chief marketing officer for UltraViolet organization.
In one week, UltraViolet leaders told 41 Action News almost 45,000 people have signed the online petition asking the Royals to stop promoting Vitae.
Kansas City Royals TV Publicity Director Toby Cook last week responded to complaints from UltraViolet, with this statement:
"We entered into an agreement with the Vitae Foundation at the start of the 2016 season. It is primarily a radio advertisement buy. Vitae has similar agreements with other sports properties and media outlets. Separate from the ad campaign and as a general manner of practice, the Royals take no official position on culturally-sensitive issues."
A statement on Tuesday from Martha Schoenberg, Vitae Foundation Communications Director explained its mission.
"The Vitae Foundation is a non-profit, educational organization that uses research-based messaging and media to inform women facing an untimely pregnancy about local pregnancy centers; educating the public about the value and sanctity of human life; and restoring the value of life as a core belief in the American culture. Vitae has used radio and sports advertising to distribute educational messages for 25 years.
"Vitae attempts to help women in difficult pregnancies find one of the 2,000+ pregnancy centers across the country. Caring pregnancy centers give women choices beyond just an abortion. If a woman in a difficult pregnancy makes the courageous decision to bring her child into the world, Vitae believes she should have meaningful support in making that decision. Pregnancy centers provide that support, and the Vitae Foundation is privileged to work with those pregnancy centers as they support women in making a decision they can live with."
