The goal of a commencement is not to create dialogue, it is to get the degree that you have worked towards for the last 4+ years of your life. What conversation did you expect the students to have with Mike Pence? He wasn't there to listen to them, and they already know his views. Mike Pence's record on gay conversion therapy may be uncertain, but he is definitely a flagrant homophobe who has brazenly attacked gay and lesbian rights. These are the words from his congressional campaign website:
Congress should oppose any effort to put gay and lesbian relationships on an equal legal status with heterosexual marriage.
Congress should oppose any effort to recognize homosexuals as a "discreet and insular minority" entitled to the protection of anti-discrimination laws similar to those extended to women and ethnic minorities.
Congress should support the reauthorization of the Ryan White Care Act only after completion of an audit to ensure that federal dollars were no longer being given to organizations that celebrate and encourage the types of behaviors that facilitate the spreading of the HIV virus. Resources should be directed toward those institutions which provide assistance to those seeking to change their sexual behavior.
To admonish students for respectfully and peacefully protesting a man with a track record of discrimination against a minority group and a record of denying science and the effects of climate change at THEIR OWN GRADUATION because "regressives are unable to even sit quietly and listen to someone with opposing views" is pretty disingenuous. Did they make noise? Did they in any way impede him from speaking? No one is obligated to listen to anyone, especially at a graduation. Furthermore we live in a democracy and if we feel unsatisfied with our elected officials (they are called public servants for a reason), we are not just allowed, but obligated to let them know. This article just goes to show that conservatives will never be happy with any form of protest taken by the left. The world is literally on the brink of catastrophic climate change and you are writing about "virtue signaling" (whatever that means) when concerned students are trying to make their voices heard with the limited means available to them.
