i don’t feel like going back to reread the posts i’m responding to, but anyway:
first of all, in order to implement this idea of boys dating younger, you would have to have rabbonim and roshei yeshiva drilling this into the boys, and u’d have to get them to come out and tell the velt that this is how its gonna go from now on. which rov or r’y is gonna do that? they want the bachurim to sit and learn!
also, the crisis is not coming from the way we date IMHO. i think its coming from a deeper “priorities crisis” if you will. i think that the priorities of many ppl are messed up and we are looking first at the superficial, rather than what’s really important. now there’s a problem that needs fixing.
