Yes, I was intending to comment on that, as well. "Accountability" isn't a unitary thing, nor are all insults equivalent, nor is the degree of offense taken by various individuals to any given insult. Unintentional wrongs surely merit less approbation than intentional ones. The law generally treats violations this way, and I would suggest that this is a human trait generally. If the insult is great enough, then we can assume a greater degree of responsibility is in order, even if we can't see the intent. On the other hand, for a minor slight, the unintentional nature of the faux pas may well may it something to simply ignore.
The example of the name mispronouncing is a good one. My wife's close colleagues have been mispronouncing her name for more than two decades, and she's never seen fit to correct them. I would have, personally, as I try hard to pronounce names correctly and prefer others show the same courtesy. But she never has seen the need to make any correction, so I simply find excuses to say her name and model the correct pronunciation for them when I'm around them, but otherwise, I keep my mouth shut. On the other hand, my wife genuinely finds some curse words very offensive, so I take a lot of care around her not to use them, even though in most contexts they don't bother me. Again, I keep my mouth shut.
Hmm. Seems like a common theme, but I'm afraid it doesn't come naturally to me.
