These seminaries must be doing an incredible job. They take a girl who has had 12 years of schooling and 17 years of parental chinuch. And in the short 9 months they have her, they radicalize her. They convince her to abandon all the wonderful values of her schooling and upbringing and instead, marry a kollel guy and live in suffering and poverty.
Or, the 12 years of schooling and 17 years of parents have done a terrible job.
