Changing the subject? You took the opportunity of commenting on one group of students of one school who were accused of misbehaving and were punished for doing so, in order to malign multiple categories of observant Jews who had nothing to do with the event and do not even send their children to that school. Throwing up names of other “categories” of observant Jews does not change what you have done.
I am glad that you have clarified that you are not a self-hating Jew.
I am not "maligning" anyone.
Nor am I changing the subject.
What I am observing is that unruly teenagers are a feature of all communities that are composed of humans.
Quite a bit of paranoid theorizing here.
