“On a personal level, if someone lost friends due to being more observant, it is also a reflection on someone’s level of observance. A true Torah scholar should cause positive emotions among at least some of their friends at least according to beis Hillel”
I agree with a few caveats:
1. A change in derech usually causes a change in focus or priorities, which may result in some friendships gradually drifting apart and other friendships becoming closer, or new friendships developing. This is a normal part of life.
2. Much of this conversation is centered on children – and children are not socially mature creatures yet. Yes we need to provide chinuch and guide them to become respectful, sensitive adults, but it’s a process.
