I understand your reaction, but you can spare yourself the anguish by understanding the statements. It is a common human frailty that we try to distance ourselves from tragedy by rationalizing “why this can’t happen to me”, most especially when the tragedy strikes close to home. Thus, these insensitive comments are really nothing more than an expression of the posters’ stress at thinking of normal frum kids (who are just like their own!) going OTD. They try to quash their anxiety by saying things like, “only kids with mental health issues would go OTD”, “only kids from abusive homes develop mental health issues”, and reasoning thus that it is within their control to prevent their kids from depression, PTSD, personality disorders, and from going OTD.
As a social worker, you need to be able to deal with and understand not only the “ones with issues” but also the “normal people”.
