I can find no connection between rocking boats and nice or not nice. I have rocked (and rocked and rocked) boats my whole life. And I dearly hope I have been nice-decent in the process. In fact I know for sure that my boatrocking would have had little effect had I not been nice. https://twitter.com/nowaffle/status/1319702855486443521

My success as a speaker is largely because I say brutally contentious things in a way that connects with people and shouts “I care about you.” I would not have made any impact hadI not been “nice.” (FYI/I repeat: I fully acknowledge significant gender differences on this topic.)
