What other parts of that article are gross overstatements?
I think every. single. person. who ever went of the derech can write the exact same article and choose any one aspect of their life to blame it on.
He chose some random reason that is a hot topic, so more people are reading it. But there's nothing novel or new about a bitter person writing why he chose to live differently than his parents.
He's a decent story teller, builds a nice plotline, antagonist, climax, resolution etc.
He should look into writing historical fiction more often.
