Jay Chou's Snail was selected as a Chinese textbook for middle schools. How to treat this incident?

Snail is the theme song of World Vision. Regardless of the tune, the lyrics are very inspirational. It's a story about a little snail who is not afraid of difficulties and bears hardships and stands hard work. This song is really instructive. Education should not be rigid and rigid. We should absorb all meaningful things and dare to innovate. Hitler was a fascist leader, autocratic and persecuting people, but his military talents were convincing. The author of articles and songs is not important. What matters is what kind of thoughts and spirit this article or this song conveys to people. Education is too rigid, thus killing many talents.
