MINNEAPOLIS, MINNESOTA – The group which successfully banned gay marriage in California has turned its sights on a mainstay of America’s breakfast table. The National Organization for Marriage (NOM), last week accused food products titan General Mills of supporting efforts to destroy the traditional definition of marriage. Brian Brown, the president of NOM, said, “General Mills makes billions marketing cereal to parents of young children. It has now effectively declared a war on marriage with its own customers when it tells the country that it is opposed to preserving traditional marriage.”

In November, voters in Minnesota will decide on a ballot measure that would amend their state constitution to ban same sex marriage. General Mills, which is headquartered in Minneapolis, issued a statement in opposition to the ban, which said, “We do not believe the proposed constitutional amendment is in the best interests of our employees or our state economy—and as a Minnesotabased company we oppose it.”

General Mills has a brand portfolio that includes more than 100 leading U.S. brands, including Betty Crocker, Yoplait, Pillsbury, Green Giant, and Häagen-Dazs. The Fortune 500 Corporation is frequently praised for its worker- and LGBT-friendly policies, and CEO Ken Powell recently spoke at a Minnesota gay pride event.

The company’s vice president of global diversity and inclusion blogged last week, “Obviously, there are strongly held views on both sides. We acknowledge those views, including those on religious grounds. We respect and defend the right of others to disagree. But we truly value diversity and inclusion—and that makes our choice clear.
