Winnie: Well stated!!!
A boy or girl is not obligated to consider how his/her decision on choosing a life-partner might affect the shidduch prospects of others. It is probably the most important single decision they will make in their lifetimes and should be driven on what works best for the two of them, not on what some CR poster might have speculated about some Fake Shidduch Crisis or how the machatonim will be outraged about a a “mixed marriage” aka litvish bochur marrying girl from some esoteric chassidus they’ve never heard of.
