I do not think that separate education is good for anyone. Feminism is tempered when girls learn alongside boys. Take away the boys, and the girls are taught the most rabid, illogical tenets of "feminism" possible. And when boys are taught in the absence of girls, they learn the most hyper-testosterone driven behavior possibly. Hyper masculine men and hyper feminist women aren't going to get along, ever. Children need that interaction with the opposite gender in order to develop properly.
Feminism is the problem, not coeducation.
