That's like saying "there's no way to remove emotion from a conversation". Of course not, emotion is always present. But adults practice emotional regulation and work hard to prevent it from interfering with relationships (i.e. not screaming when you're angry).

Sure, politics colors many people's worldview and it's hard for them to put it in a box - that means we shouldn't try?

In a better world, we'd focus on critical thinking, being less sure of yourself, openness and active listening. We'd teach people to work to think objectively and to identify the differences between technical opinions, emotional and political ones.

We wouldn't say "well, this is hard, so let's just do whatever".
