The OP asked if these Easter boxes, wooden crates full of gendered stuff, were a "thing" which they weren't in my family or the area we lived in.
They're gendered? Never mind. Crates featured several other posters' childhoods, so your declaration that they haven't been around very long is...weird.
I suppose we could pull apart the use of the word "forever" so that someone can make a victory point on semantics that doesn't actually apply to the essence of the argument. But taking it as the rhetorical device it clearly was, I assumed we had all taken it to mean "with a relatively established history, in that they are not new to this generation". I don't think anyone thought it was intended to mean "they didn't exist in the Ice Age" or equivalent. If that was the intention, I think we can all agree that they didn't. But they did exist in some people's past, your own not being the final and only authority on what all families in history have done, and that's really the point that was being made. For many people, they aren't new. They are repeating their own childhood tradition.
And even if they are new...so what? What's the moral value to it? If you want to moralise about newer things that are bad for us, go after fast fashion, the exploitative tech sector, excessive single use plastics and all the other things that really ARE the problem...or would that require too much change for you?
