chief > You believe that Charedim shouldn’t go to the IDF, fine. It’s understandable. Just don’t treat Religious Zionists who do enlist as Ovdei Avodah Zarah.
Unfortunately, as we see in these discussions, it is hard to maintain respect to others while advocating isolationism. If you recognize value of soldiers, then you will have to allow at least some from your community to join. In other words, to maintain strict boundaries around your community, you need to convince people that everything outside is treif. So, we have a method that works in social terms, preserving community from assimilation, but it leads to creating philosophy that does not always reflect Torah values.
