As a mom, I have a few simple goals for my son. I want him to be safe and healthy. I want him to be honest, empathetic, and kind to everyone he meets, to stand up for himself and anyone else who is being mistreated, and to feel the deep joy and fulfillment that comes from being his own best self. None of that is gender specific, which is why I find it frustrating that people, particularly men, are already trying to stuff him into the “man box.” There are certain things no grown-ass man should ever say to my son, for any reason, because they have nothing to do with being a good person, and everything to do with a set of bad ideas that make life worse for people of all genders.
Presumably, my son is cisgender, though we honestly won't know for sure what his gender identity is until he gets old enough to understand it and tell us. Regardless of what that turns out to be, I want him to have the freedom to define that for himself, rather than feeling pressured to act a certain way because of what other people believe about people who were born with similar body parts to his. I also don't want people telling him things that suggest he's only allowed to feel certain feelings, or that he can only pursue interests they think are for people like him. It makes my job as a mom a lot harder when other people try to teach him to hide or otherwise lie about what he thinks, feels, and likes on a regular basis. Pretending to do and be only the things society assigns to your gender is not a path to being an honest, fulfilled person.
Also, if #MasculinitySoFragile that random dudes feel threatened when a toddler doesn't “act like a man” while out in public, then the whole concept is overdue for an absolute destruction. If the future of "manhood" rests on whether or not my son cries after dropping his free sample at Costco, it belongs in the trash can of history, next to his dirty bite of ravioli.
