Engaging people and meeting them where they are, with honest discussion, can sometimes turn an ardent detractor of something positive into an ardent supporter of something positive.
"Ardent detractors" aren't the people I'm talking about. I'm talking about bad faith actors who understand exactly what is harmful about their position and are choosing that position anyway, because their incentives are aligned with maintaining the harmful situation. These aren't people you can engage in good faith with precisely because they will use your assumption of good faith against you.
