1. I haven’t read the article and have no interest in doing so, but it is never okay to refer to another Jew as “despicable”, particularly during The Three Weeks. THAT is appalling!
2. It is also inappropriate and halachically problematic to refer to someone as Chareidi if their views do not reflect the Chareidi position (since it implies that this is the Chareidi point of view.)
3. If the boy was interviewed “on the spot”, it is certainly inappropriate for anyone to be writing about him and attacking him.
