(CNN) The public outrage over the "religious freedom" bills recently passed in Arkansas and Indiana caught the governors of those states completely off-guard, judging by their confused and contradictory responses.

As poll watchers, they surely knew that most Americans now oppose the discriminatory laws and practices they accepted as normal only a dozen years ago . But the politicians underestimated the pushback organized by local and national businesses, including companies with no previous record of public support for social equality.

They had better adjust to a new reality.

For the past three decades, socially conservative evangelicals and pro-business interests have been powerfully allied against government regulations, environmental initiatives and social welfare programs, while supporting lower taxes for the wealthy and pushing back against the growing diversity in America's population.

For many, this alliance been puzzling: Other, equally devout Christians who place more emphasis on Jesus Christ's message of unconditional love and on his denunciations of excessive wealth and neglect of the poor, have been uncomfortable with it, as have many business leaders. Their priorities, after all, are based on the bottom line. And companies that sell goods and services to the public are learning that support for discrimination -- or even passive acceptance of it -- threatens that bottom line.
