n0mesorah,
“I don’t know if that would work. You don’t make strong balei teshuvah through hashkafa battles.”
I don’t think AviraDeArah was suggesting to wage a “hashkafa battle” with a potential BT, but rather to explain Jewish values clearly, honestly, and (most important) respectfully. This is not an easy thing to do, but if Jewish values are misrepresented in an attempt to make frumkeit more palatable to someone with a very different values system, they will ultimately feel betrayed.
