Myfriend, that’s you again.
1) Nobody says that people should learn secular subjects to be civilized. The Jews need them to be able to have normal parnosa, and not to have to be mechallel Shem Shamaim like in E.Yisroel.
2) If uncivilized and primitive is so good, why then Moshe Rabbeynu tried to change that by teaching them about having two meals a day?
3)This whole “let’s be backward” approach was tried in Europe. It did not succeed.
