The point is if its beyond their behira its not bemezid. Besides, Bmezid means that the person is doing it on purpose to anger Hashem. Meaning, they understand what it means to not sin against Hashem and they know the consequences and are doing it anyways. Meaning, having a strong Emunah and STILL sinning with the intention of angering Hashem. That’s Bemayzid.
Most OTD kids are clueless in their yiddishkeit and never had a strong foundation in Emunah and what Yiddishkeit is all about. You see we have read Rabbi Kaplans works and all that. They have not. Understanding this it should be clear that hey act out from a place of pain and hurt they have no real clue what they are doing. You can’t act out against Hashem when you don’t really know who what He is…That’s NOT Bemayzid at all.
