As I see it, the issue with Rabbi Starr isn’t so much what he did sexually (and we don’t really know exactly what he did and with whom). It’s that he was so ashamed of what he did that he was willing to comply with a blackmailer to the tune of half a million dollars.
The fact that a 16-year-old boy left his house and traveled to New York without telling his family or friends is not okay. Something is amiss. It may be mental health issues (depression, anxiety or some other problem), sexual identity issues, abuse issues, or any number of things. But the fact is: everything is not fine.
