“But even more disturbing than the threats from foreign terrorists is a second threat that is right here at home,” he writes. “It is an ideology so fundamentally at odds with historic American values that it threatens to undo the cultural ethics that have made our country great. I call it ‘secular-socialism.’

“The Left has thoroughly infiltrated nearly every cultural commanding height of our civilization,” he says. “That is, they hold power, influence and control of academia, the elite news media, Hollywood, union leaders, trial lawyers, the courts, the Congress, and the bureaucracy at all levels of government.”
