Was it wrong for them to try to market towards a demographic that largely ignored them even when being gender neutral and being successful for it?
As well if their product clearly spoke to girls and women if it sold so well. So it isn't like they made a product no one wanted.
Morality completely divorced from practicality has no leg to stand on. This holds true in all societies no matter how saintly.
Legos For Girls is more an exercise in how we wish the world was better, but it isn't.
Especially since, as people have demonstrated earlier in the thread... Legos were advertised and printed with male and female children playing it for decades. They also never stopped making gender neutral lego sets.
Don't get me wrong, I am not happy about it at all... but in order to have a full argument for Lego NOT to do it, I need something more then simple moral outrage. Since telling them NOT to do it, is pretty much telling them not to make money because of some intangible harm it MIGHT be doing to gender roles.
For movies and videogames for example, I usually try to include arguments about story variety and quality. As well that statements on "how unpopular female lead videogames are" are based off of those CRUDDY female exploitation games that were NEVER going to do well. Though they could bring up Beyond Good and Evil >_>... But given Psychonauts was in the same situation...
Honestly part of me wishes Beyond Good and Evil wasn't a thing, even though it is a totally awesome game... because if there was ONE game, game executives could hold over our heads and go "Ha See! Women make everything worse!" it would be that. >_<
