February 24, 2021 Domestic political and cultural divisiveness has become the United States' greatest strategic weakness. This grim vulnerability, exploited by international rivals and authentic domestic enemies who despise the U.S. Constitution, puts the U.S. republic in peril. Let me provide a background example. Left-wing 1960-ish feminists politicized the personal. Demonizing men as innate aggressors was a cool political tool. The feminist propagandist portrayed herself as something more than a reborn 1912 suffragette demanding the vote. She was a systemic victim of the patriarchy, an oppressive, predatory sociocultural, political and American structural scheme concocted by males to marginalize human females. Somehow the scheme (always hazily defined) managed to oppress British queens and female New York millionaires.
