Lomed, your statement about non-Jews it ignorant. Propogating ignorant statements is a huge factor in the OTD crisis. “The outside world has nothing real to offer” and “People don’t connect to G-d” are false, false, false. If the kid goes searching and sees there are people with real, fulfilling lives and those who are close to G-d without keeping halacha, are they really going to believe you?
I’m laughing at “if I had a deeper understanding of Judaism” – I do have a deeper understanding. That’s why I understand kids who go OTD for intellectual reasons. Why? The Torah cannot be proven 100%. It takes faith. If you don’t acknowledge that, they will start googling and find a wealth of information that tears apart the “proofs.”
No one goes OTD for seeing improper images. They may use it as an excuse “Well, I want to watch pornography so let me go OTD” but in reality, there are men out there watching it while married or single (don’t believe me, check out the many threads on imamother.com about it) and still frum.
Its normal to struggle with a taivah. But people don’t break away from Judaism because of it.
