Oomis,
Your “theory” that we should encourage socializing to end the shidduch crises, and that the crises is not caused by age gap, is wrong for several reasons.
1) Socializing is assur, plain and simple. It’s not a “yeshivishe chumra” or anything of the sort. Just basic halacha.
שו"ע (אה"ע סי' כ"א סעי' א'): צריך אדם להתרחק מן הנשים מאד מאד וכו' ואסור לשחוק עמה ולהקל ראשו כנגדה
In case you think “socializing” is not included, see what is said about going in mixed company to Tashlich.
אלף המגן תקצ"ח ז': ויש לבטל המנהג (אותיות גהנם) מה שהנשים הולכות ג"כ לתשליך, כי באין עי"ז לערבוביא הנשים עם האנשים ואוי לעינים שכך רואות ביום הק' הזה
2) There’s absolutely no reason to associate socializing with higher marriage rates. The chassidim are strictest when it comes to segregation, and they have no shidduch crises. The modern orthodox who believe in socializing have a worse problem with older singles than do the chareidim.
3) The age gap is most certainly true; it’s plain math, and the numbers don’t lie.
It’s ironic that you seem to feel that NASI is insulting older girls, but you don’t have a problem insulting the entire yeshiva world (not capitalized) by insinuating that we’re socially inept and can’t function on a date without mentoring. I’ll have you know that most of us, without any socializing before dating, somehow manage to function fine on dates, marry successfuly, and raise families.
tahini,
see point 1) above. Two more quotes:
מסכת אבות פרק ב משנה ד - הלל אומר… ואל תאמן בעצמך עד יום מותך
כתובות יג - אין אפוטרופוס לעריות
It has nothing to do with being "modern orthodox", it'a a matter of ignoring the words of Chaza"l.
