This kind of writing is dangerous because it goes beyond (mere) argumentation; it becomes immersion, method acting, dual-booting. To make your argument strong, you have to make your opponent’s argument stronger. You need sharp thinking and compelling language, but you also need close attention and deep empathy. I don’t mean to be too woo-woo about it, but truly, you need love. The overall sensibility is closer to caregiving than to punditry.
This is about the debating technique whereby you first restate your opponent's argument to their satisfaction, before making your own.
