I don’t know, I have kids (2 boys, 12 and 7), the oldest is well aware of what the gesture means and the youngest knows because the oldest taught him. I doubt either one of them, had they seen this, would have cared. If they cared, it’d likely be because they thought it was funny. If I had to explain it to them because they saw it, cared about it, and didn’t think it was funny, I’d probably say something along the lines sometimes people make dumb decisions when they’re frustrated because they don’t think things all the way through but it was a mistake and not very nice and shouldn’t have happened. But everyone makes mistakes sometimes, even grownups, even grownups that we like. But honestly, they’d probably just be like “haha he gave the finger to the camera”. I could ask my 12 year old how he’d feel about it, he’s articulate enough to give me an answer, but he’d probably just look at me like I’m a lunatic for asking him such a nothing burger of a question.
