I honestly don’t know why you’d expect these people to be sensitive to the memory of dead people who petrol‑bombed them, cut off their water supply, shot at their windows with crossbows and subjected them to a campaign of harassment and intimidation.
That’s not a “normal disagreement” — that’s sustained, deliberate violence.
When you’ve lived through something like that, you don’t owe the perpetrators reverence, softness, or silence. You owe yourself whatever helps you survive it.
Writing about it isn’t “weird”; it’s a trauma response. It’s a way of reclaiming control, documenting what happened, and refusing to let the people who terrorised them also dictate how they heal.
It’s not for you to decide how they deal with their trauma. Calling their coping mechanism strange while downplaying the severity of what they endured is the part that’s actually odd.
