My four decades of experience with secular Jews taught me this lesson:
Nothing is more futile than attempting to influence secular Jews in the direction of mitzvah observance. It is a total waste of time, 99.95% of the time.
Charedim refusing to serve in the Israeli Army has made the Charedim the most hated people in Israel – even more hated than the Arabs!
Add to that the many scandals involving Charedim, that make Charedim even more hated.
Add to that the high percentage of Charedim in Israel who do not pay taxes because they do not work, this makes Charedim even more hated.
Charedim cannot influence secular Jews to mitzvah observance, because Charedim are the most hated people in Israel.
Instead of trying to improve secular Jews, Charedim should try to improve themselves.
