There’s a lot as a society we can disagree on. We should. Conflict itself can open space for hidden things to be revealed. It can be a place where the transcendent is discovered. In the Christian faith conflict becomes a space where the Lordship of Christ can breakthrough in transforming ways, calling each participant to an ethic of love. So yes, we should disagree freely, but without the trope of American Liberty being invoked (after all, many of us like free speech a lot less when someone says something we don’t like). We can disagree because it’s good.
But can we at least agree that we should have a human ethic to do no harm? If we cannot agree with that conflict will continue to be mechanized for violence. Violence hurts us all.
