You should know that armies have rules. In most armies of the western world, there is a rule that hair has to be a certain length and beards are a no-no. This is the rule in the United States as well- would you call the U.S. army comparable to the nazis chas v’sholom?!
In the United States, there have been a string of court cases about religious muslims and sikhs that want to keep their beards and most of the time they get to. However, it takes time to change the army’s rules. I hope Israel will change the rules, but you have to be patient. You cannot barge in and expect everyone to do everything you want at the moment you want it. What chutzpah.
