Kyle Cupp explains:
For the most part, culture war rhetoric is aimed not at offering an effective proof for the benefit of the opposition, but in destroying the opposition. Because proof is not its aim or its concern, culture war rhetoric has no allegiance to the truth. This isn’t to say this rhetoric necessarily employs lies, but that lies are not antithetical to its purpose. Its loyalty is to whatever most effectively leads to the enemy’s defeat. It employs famine, sword, and fire and suffers nothing if it sickens, slashes, or engulfs the truth as collateral damage.
