Is it HER fault that her parents couldn’t make their marriage work?
No, Oomis. Is it ANYBODY’S fault that they’re BT, ger, blind, deaf, diabetic, epileptic, ugly, fat, divorced, widowed? Not usually. Can they expect a flawless shidduch? They can certainly hope – stranger things have happened – but shidduchim work in capitalistic fashion (supply & demand), and they (and everyone else) need to keep their expectations realistic.
BTW, I wish you’d read the whole thing, including Observanteen’s responses, before you criticized. IMO she did not at all come across as smug or condenscending, and she retracted her term “second rate”.
