“Why is it that people reject shidduchim suggested to them because the family is balei teshuva? Isn’t it something to be proud of? Whats wrong with marrying in to such a family? Shouldn’t they be accepted like everyone else?”
Didu, I couldn’t agree with you more. And I don’t only talk the talk but I walk the walk.
But the main reason why FFB families run away from ba’alei tshuva shidduchin is hypocrisy from on top. While there are a few exceptions, the majority of Rabbonim and kiruv professionals in the Orthodox world, while they advocate FFB/ba’alei tshuva marriages, will not have their own children marry ba’alei tshuva. If this were not the case, you would find the acceptance level vastly higher.
