Having spawned and suffered from ideologies like fascism and communism, post-WWII Europe became deeply skeptical of passionate belief systems. This cultural exhaustion favors moderation and process, a stark contrast to rising ideological fervor in the US.

Contrary to popular belief, Christianity's monogamy isn't rooted in Judaism, which practiced polygyny. Instead, it was a strategic adoption of the prevailing Greco-Roman norm, a move crucial for the new religion to be taken seriously and spread within that society.

Even for atheists, cherished Western ideals like tolerance, mercy, and humanism are not universal; they arose uniquely from Europe's Christian milieu. These values are a cultural inheritance, not a defiance of religion, and are fragile without their originating context.

A key transformative act of the Reformation was Martin Luther's push for clergy to marry. This dethroned the celibate monk as the pinnacle of Christian devotion and elevated the married pastor and his family as the new, accessible model for all believers to emulate.

Merkel's experience in East Germany, where over 90% of women worked full-time, normalized professional interaction with men. This background gave her an advantage in navigating the 'stuffy male environment' of West German politics, making it an easier transition than for many of her Western female counterparts.

The falling birth rates in many Western nations are a direct consequence of economic pressures. Young people are postponing or forgoing having children because the high cost of housing and living makes it financially impossible to start a family, a phenomenon exemplified by adults in their 30s still living with their parents.

With only 4% of Democrats marrying Republicans, political affiliation is becoming a hereditary trait. This lack of inter-group marriage solidifies the divide, turning political ideologies into distinct tribes akin to historical religious or ethnic splits, hardening polarization for generations.

Thatcher's politics were uniquely shaped by the Methodist values of her father: hard work, thrift, and a clear line between good and evil. This infused her rhetoric with a moral certainty and evangelical fervor that was unusual for a Conservative leader.

Data showing conservatives are more charitable than liberals is misleading. The driving variable is religious activity, which has historically been correlated with conservatism. As a segment of the political right becomes more secular, this giving gap is expected to shrink.
