Secular Jews “don’t have any satisfaction in their life,” Yosef says. “A person who eats non-kosher food, his brain gets stupid, he can’t understand things, doesn’t get it. As soon as he starts keeping kosher, you can start to influence him.”
Yosef says that secular Jews are “jealous of [Haredi Jews], it’s all jealousy… it all comes from jealousy and becomes hatred.”
