> Yeah, I personally think this feature-removal is just plain sexism.
It probably had nothing to do with sexism per se; rather it probably was a business call made by people who suspected that while some percentage of girls would like that feature, a certain percentage of parents wouldn't find that feature appropriate or scary or simply not something they would consider as suitable for a toy. These people are paid to know their target demographic and to make choices that maximize profit for any given product.
Their assumptions might be rooted in sexism, but I suspect that most of their frame of reference consists of simply knowing how parents and relatives view these products, their sexist attitudes included. That is to say, if these people suspect that a significant percentage parents want to stimulate exact thinking and problem solving skills in their girls, they will translate that to market decisions (which is slowly happening now).
