popa: Early in the thread there was an attack on the way of life practiced by the posters you reference (prior to either of them even commenting here.) You hadn’t protested that attack, yet here you are full of protestation, with the shoe on the other foot.
In any event, to the best of my knowledge (and I stand to be correct otherwise), the current dating practices you and I practice have no basis in traditional minhugim that are supported by gedolei acharonim, but rather are an American developed system. I don’t see anything the two posters you criticized said, that is beyond the pale of discussion.
P.S. You can also criticize Rambam using words straight from the gedolei rishonim. Nevertheless, as in our case here, both Rambam and his dissenters have subsequently been fully accepted in the Torah world, and reviving any criticism of old is both invalid and counterproductive.
