I actually though this was an Onion article when I saw the headline. I have no idea why this should at all be considered news. They dressed up the kid in girls clothes for laughs, big deal. Unless the kid was extremely upset about this and resisting, I don't see why this is such a huge issue. It's just fabric!!! I saw another article about how they are making a "political statement" by doing this. Gender expression is not a "political statement". By labeling it as a "political statement", the cis-patriachial society is just pushing us further to the margins by reducing our issues, needs, problems, and experiences into a "political issue" rather than something that affects our lives and the lives of our loved ones.
ETA: Also consider that if they dressed up a girl in a boys' clothes, nobody would care. You know why? It's because women and girls are viewed by our society as being subordinate and inferior. If you dress up a girl in boy's clothes, it's not shocking at all because they are putting her in a superior position by doing so. The reason why vice versa is considered to be so shocking is because they're putting the boy in a subordinate position. This is obviously evident even from the article, which describes it as "humiliating". That is why people think it's abusive, because as far as the patriarchy is concerned, taking away a male's masculine superior status is pretty much like crucifying him.
Ugh I've had enough misogyny, homobigotry, transbigotry, and gender policing for one day.
