The conservative American Family Association’s website, for example, listed some of the many well-known corporations that are now supporting same-sex marriage — including Google, Microsoft, Citigroup, Apple, Nike, Facebook and Starbucks. The website suggests that Americans opposed to gay marriage should boycott these companies, but the president of the Mississippi-based association, Tim Wildmon, acknowledges that would be impractical.

“There’s too many of them to effectively boycott,” he said in a telephone interview.

Wildmon expects the U.S. to remain divided over gay marriage for a long time and hopes neither Congress nor the courts try to interfere with the right of states to set their own policies.

“That’s just the way it’s going to be,” he said. “If you want to be a homosexual married couple, move to a state that accepts it.”

Such interstate moves could indeed occur, but with a potential cost for the states being forsaken, said gay rights lawyer Jon Davidson of Lambda Legal. “Maybe that’s what some states want, but the outpouring of business support for us indicates a lot of businesses don’t want that to happen,” he said. “It creates all sorts of problems.”
