I focused on the part of the comment that I was replying to that I disagreed with.

Without wanting to be overly reductive, this is the point of discussion: to focus on the points of disagreement, for the purposes of understanding, alignment, or persuasion.

I would have thought that this was obvious, and how people expected discussions to work. I would have said that needing to be thorough and explicitly state each point of agreement, alongside addressing the points of disagreement, was frustrating and unnecessary. But maybe I'm wrong on this, so thank you (genuinely) for giving me this to reflect on.

(RE: "triggered" - maybe re-read what you wrote. Responding to an ostensibly benign comment about the background cause of Kamala being chosen as the candidate, with "such a wonderful way to keep attention focused anywhere but on the almost half the country still supporting a murderous cabal filled with people covering for a bunch of (other??) people who raped children to get pleasure from the sexual torture" certainty comes over as disproportionately and inappropriately emotional and angry in word and tone, to this observer.)
