In the 1950s and 1960s, Americans argued most often about foreign policy, racial injustice, and the economy. Since that time, they have also quarreled over beliefs and values, especially as patterns in family life have become more varied. In substantial measure these conflicts were rooted in the social and cultural changes of the 1960s and 1970s that had altered traditional institutions. Changes in roles and expectations among women and new openness about gay and lesbian sexuality were particularly powerful in dividing American churches and politics. Abortion rights and the conservative backlash, the increase of women in the workforce, and the new "culture wars" were part of modern America.
