I heartily agree with this article - it's a bit of sanity that is much needed with all the push lately for extreme gender neutrality. The Swedish principles are currently being discussed here in Germany as well and are proving popular (though it most likely won't be as extreme for a while).
The flip side to all of this of course is the silly "LEGO Girl" product where they apparently forget that girls can (and do) build just as well as boys and instead market little Lego kitchens and household appliances instead of cool bricks.
But swinging from one sexist extreme to the other is not the way to go.
