This is what we found on Wikipedia regarding the Culture Wars:

A culture war is a form of cultural conflict (metaphorical "war") between different social groups who struggle to politically impose their own ideology (moral beliefs, humane virtues, and religious practices) upon mainstream society, or upon the other. In political usage, culture war is a metaphor for "hot-button" politics about values and ideologies, realized with intentionally adversarial social narratives meant to provoke political polarization among the mainstream of society over economic matters, such as those of public policy, as well as of consumption. As practical politics, a culture war is about social policy wedge issues that are based on abstract arguments about values, morality, and lifestyle meant to provoke political cleavage in a multicultural society.
