I think the PJMedia’s article says it all.
Here are some excerpts from the article describing what the controversy is all about.
On Thursday, the evangelical Christian school Taylor University announced it had invited Vice President Mike Pence to give its 2019 graduation speech. A tremendous uproar ensued, with students and alumni reporting that the decision made them “sick” and expressed support for “hate” and “harmful bullish*t.” The school told PJ Media it would not yield to pressure and was still proud to have Pence speak at graduation.
“Inviting Vice President Pence to Taylor University and giving him a coveted platform for his political views makes our alumni, faculty, staff and current students complicit in the Trump-Pence Administration’s policies, which we believe are not consistent with the Christian ethic of love we hold dear,” Alex Hoekstra, a former staffer for President Barack Obama and a 2007 Taylor University graduate, said in the petition.
