The rule is not meant to attack people who make good-faith mistakes/unintended consequences. It instead is intended to stop defending people who make ill-intentioned comments and attempt to hide them as mistakes; or who refuse to back down from a mistake even after being told it was a mistake. For example, if someone from Eastern Europe says something like "it's alright 'cause it's all white", someone from the USA who knows the history of this phrase may take offense. If the person from the USA feels that this may have been an attack, they should be free to raise this issue, and the person from Eastern Europe should apologize for making them uncomfortable, even if it was unintentional. As long as they do this, no further harm should happen to either person. However, if the person who made the comment refuses to apologize/explain, or keeps repeating this comment since "to me it's not offensive, it's just a joke/reference" etc, then this should be considered a problem and someone with authority should intervene. Similarly, if the person who took offense refuses to accept the mistake after an apology or explanation was given, then once again someone with authority should intervene and correct this error on this other side, as it unnecessarily creates a hostile working environment. This is the intended reading of that line. Of course, that line can also be mis-applied by immediately punishing the person from Eastern Europe in my initial example. Note: I used "person from Eastern Europe" in my example because that is where I am from, and because I have personally seen others around me using references to US culture without knowing the full context in just this way, without ill intent but in ways which would probably shock someone who assumes that the context is well known (for example, casually addressing peers using rap lyrics containing the infamous N-word).
