I do think being assertive can be helpful in any situation. I also do think this is common sense, but then again, common sense is not that common nowadays. And even if it's easier to act aggressively or just not say anything, as you mentioned, this will just lead to people storing anger that will burst in the most inappropriate moment. I think it's easy to make people understand what assertiveness is and how to enact this behaviour. But the hard bit is not this, is making people understand they need to learn this. And I think giving them day to day examples as the one you gave is helpful, because as long as they can relate to something, they will understand easier. Also, things as gender can not be considered relevant to this topic. It all consists in the way you've been raised, the education you've had and they way you learned to solve your issues.
