The biggest proof of how disingenuous AZ, DY, and all of NASI really are is this conversation with ubiq. He present a problem that is indisputable (on “shidduch island” even 112 girls to 100 boys should lead to all girls getting ample dates) and they say “We could argue about that forever”. Note that ubiq isn’t even contending the age gap or any other NASI dogma, he is accepting their dogma as fact and then going a step further (or to the side perhaps), but even that amount of intellectual honesty is not to be found with them.
Off of the island, aka the real world, this is also true. There will always be some folks who will not marry and some who will never land a date (except a 100% blind one). This doesn’t go against anything NASI stands for, so I can only think of one reason why they would fight against the acknowledgement of this point.
