"For a boycott to be successful, we have to ask people to do things against their economic interests," said Maurice Schweitzer, a professor at the Wharton School of Business. "People are going to visit Disney or not. They are going to visit Grandma or not."
Boycotts require a commitment, such as when the Rev. Martin Luther King Jr. led a successful boycott against buses and other public transportation in Montgomery, Alabama, in the 1950s as part of the civil rights movement, experts said.
A clear and simple goal must be present, with "a protracted feeling of outrage," Pizam said.
Remember how Americans boycotted French wine after France declined to join a U.S.-led coalition to invade Iraq in 2003?
"The feelings that we have today are not the feelings that we're going to have in six months," Pizam said. "Just as we were upset at France and might have chosen an Italian wine over a French wine a dozen years ago, I think you would be hard-pressed to find an American avoiding French wine."
Boycotts can backfire, such as when the president of Chick-fil-A provoked a consumer boycott by denouncing same-sex marriage and saying his fast-food chain backs the traditional family unit.
Traditional family supporters, however, organized a counterboycott -- a "buycott" -- and even a "Chick-fil-A Appreciation Day."
"There were some groups that went and actually started frequenting Chick-fil-A more," Schweitzer noted.
Corporate boycotts can yield more immediate results because CEOs can act faster than elected lawmakers, but the activism requires key ingredients: Consumers must care, customers must be able to easily shop elsewhere, issues must be understandable, and the boycott needs mass attention, often enhanced by speedy social media, Diermeier wrote in the Harvard Business Review last year.
One successful effort was Greenpeace's 1995 boycott of Shell -- a specific target -- which reduced sales in Germany by 40%. The "McCruelty: I'm Hatin' It" campaign by the People for the Ethical Treatment of Animals, however, has had "limited impact" on McDonald's because the issues are "complex and not intuitive," especially in comparison with the more easily grasped notion of a fur boycott, Diermeier wrote.
The analysts were pessimistic about a successful Florida boycott, even if Wonder is calling upon fans to avoid doing business in Florida and any other state with a "stand your ground" self-defense law.
King, the civil rights scion, is also weighing a multistate boycott, such as against Georgia peaches because that state also has a "stand your ground" law.
"These are things that my father considered in his era," King said.
But a Florida boycott faces overwhelming odds because it lacks an easy target and uses economic pressure to seek political change, experts say.
Moreover, the gambit may even hurt African-Americans and other minorities because they often work in the Sunshine State's vast tourism industry.
"Business will suffer the least, and employees will suffer the most," said Pizam, the Florida tourism professor. "It's good-intentioned people who don't realize the unintended negative consequences that will hurt the ones they want to help."
Added Schweitzer about a Florida boycott: "It's ridiculous. It's an expression of frustration, and I think that frustration is valid.
"But I don't think there's sufficient groundswell to motivate a campaign that a boycott would require," he continued. "For boycotts to be successful, people have to have easy alternatives. Either you're going to visit Grandma, or you're not. And there aren't easy alternatives."
