数学辅导教材也分“性别”？

Recently, the East China Normal University Press (ECNUP) published a math textbook for junior high school students. The blue version was for boys, and the red version was for girls, which brought about a heated discussion online. Some people thought the book was acceptable and followed the principle of “teaching in accordance with aptitude (因材施教)”, but others  thought it was “disappointingly” sexist. Would you support the publishing of this kind of textbook?
