I know it was tongue in cheek, but to respond directly, intent doesn’t matter when the result is universally harmful. The recipient shouldn’t have to ignore the harm just because you didn’t mean anything by it. I can have the best possible intent when telling someone they are fat out of concern, but it doesn’t mean the result isn’t harmful.
FYI i’m slightly on the spectrum and it took me a very long time and destroyed a lot of relationships before I understood this. I used to believe similar, and even assumed good intentions most of the time. The problem is many people do not have good intentions a large percent of the time, and there were situations where I went years without realizing people were being extraordinarily mean to me who I thought were friends. either side of it, I just don’t think it’s a great philosophy.
The first time I ran into this was working at Meta, where that was one of the core values (it's since been replaced by "Be direct and respect your colleagues"). It was one of those slogans that sounded fine on paper, but in practice, it was almost exclusively weaponised by powerful folks to excuse their transgressions.
Think someone is sexually harassing you? You are clearly not assuming good intentions on their part. Think they are being racist towards you? Same thing. Think someone is sandbagging your promo for personal reasons? Ditto...
Your examples sort of underscore why “assume positive intent” matters a lot for how you engage but not a lot about what you engage on.
Working against the feigning surprise thing, if somebody says “oh I don’t know what DNS is”, the problem isn’t with offering to help them understand DNS, it’s leading in without projecting shock/alarm.
If somebody is blocking your promo, assuming positive intent doesn’t mean you just let them do it, it means you escalate by focusing on the root issue (“this person is affecting my promo and they’re not giving me any actionable signal as to why”), not speculating on their intent.
