Exactly. As an example, I'm transgender. While most feminists are very supportive of trans rights, there's a tiny minority, the TERFs, which see gender identity as a radical ideology and trans women as men appropriating femininity and invading women's spaces. I spent months debating in good faith with TERFs on the internet, and it did a number on me. They're quite articulate, but they don't argue in good faith - they bully, they dehumanize, they aren't willing to be convinced or see the human behind the text. And I can't debate in good faith either - I know I'm a girl, I needed hormones and transition to keep myself from suicide, I can't change my view at all! So it became a war of words.
So many of these conflicts have smoldered for decades and they're now coming to a head. Maybe the US isn't so backwards in its discourse, we might just be the front line of an ugly but inevitable war.
Then, for some, you are dealing with an "other side" that represents an existential threat. Do you listen to seemingly-rational statements from someone who, at turns, has suggested it would be better for you or people like you to starve, or be killed, or be thrown in jail? If character speaks to the intention of an act, can an act that seems righteous still be trusted?
Do you see how this can become complicated very quickly?
