I agree, more legos.
As for the topic question: Problem is, almost everyone is going to push their gender agenda on children. Boys and girls are often treated differently, and rewarded differently. The woman that takes 2 hours to get dressed annoying? Blame her parents and teachers for praising her more for how she dressed and looked, rather than praising her for what she did, or what cool thing she found in her pocket.
The most disturbing thing I ever saw was a parent of two kids, boy and girl. They ran up some stairs and fell into a heap. The father first went to the girl, and consoled her as she began to cry. The boy started crying and the father just turned to him and told him to "stop crying or he'd give him a reason to cry". WTF...
So in answer: It depends on if they are applying the correct agenda, which is to treat the boys and girls without regard to their gender.
(Hell I believe if a school imposes uniforms, they should be exactly the same for both girls and boys.)
