In February 2018, Stowe joined the Pax Christi USA Board as their president. In January 2019, Stowe wrote an op-ed that criticized Nick Sandmann and other students from Covington Catholic High School for sporting apparel supporting President Donald Trump during the 2019 March for Life rally in Washington, D.C. He said the slogan "Make America Great Again" on their clothing "supports a president who denigrates the lives of immigrants, refugees and people from countries that he describes with indecent words and haphazardly endangers with life-threatening policies".
