In the four days since Bruce Jenner came out as a woman named Caitlyn, many Americans have celebrated her transformation as a courageous and, even, heroic act.

But among the social conservatives who are a major force within the Republican Party, there is a far darker view. To them, the widespread acceptance of Jenner’s evolution from an Olympic gold medalist whose masculinity was enshrined on a Wheaties box to a shapely woman posing suggestively on the cover of Vanity Fair was a reminder that they are losing the culture wars.

Across social media, blogs and talk radio this week, conservatives painted an apocalyptic view of America. They said they felt frustrated and increasingly isolated by the country’s sudden acceptance and even embrace of transgender people. They see it as immoral and foreign. They drew comparisons to two darkly futuristic novels, George Orwell’s “1984” and Aldous Huxley’s “Brave New World.”

“People feel like they’re under siege and that the terms of the debate are now you either applaud it or you’re a bigot,” said William J. Bennett, education secretary in the Reagan administration. “It’s like American culture is being dragged kicking and screaming not only toward acceptance but approval.”
