Where does this argument end? Are we banned from using analogies containing animals because someone out there has a relative who died from a bear/shark/bee sting? Are we banned from talking about cows in a debate with vegans because someone lost a loved one when they were out hiking and got caught up in a cattle stampede? Are we banned from mentioning cars because everyone knows someone who had a traumatic car injury? By this logic you either end up molly coddling the entire world into silence because everything is a possible traumatic trigger to somebody or you declare yourself the king of acceptable debate and only the topics you approve of are acceptable because you are the chosen one anointed by the heavens.
