However, the other part that is being ignored, is that I have had some teachers at “seminary A” whose husbands did some form of sherut leumi and today are chareidi rabbis. That is also not told to anyone- including most chareidim.
Of course not! If the other charaidim would know, then these “rabbis” would no longer be accepted, their children would be kicked out of school, and their daughters unable to wed. Shunning is a superior tactic in an insular community.
