My Brooklyn community has an organization for kid who are at-risk or OTD, and there is the guilty secret: the majority come from BT homes.
BTs are handicapped by lack of family support or tradition. Also, many carry baggage or fail to “fit in” due to demeanor or behavior. According to my observation, the ones who do best came from traditional or socially conservative families, or have frum relatives, or have money (which will raise anyone’s status).
