I think the point is that you may indeed have a problem, despite your best intentions. Nobody knows what will offend or make another person uncomfortable these days. Sure, there are standard things that everyone agrees is wrong. But entirely innocent conduct can be misinterpreted, people project their own biases and assumptions into those interpretations, etc. In the MeToo era, that can be enough to destroy a career.
