I repeat my challenge: What other chiyuvei d’oraisa are we willing to disregard because we lack maturity?
I you call any shadchanim in the Litvish and Lubavitcher communities they will tell you that there is a shortage if boys, but in the chassidish world, there is no shortage of boys. The reason for this is obvious to anyone who is open to evidence.
I have spoken to two Roshei Yeshiva but they hung up on me. They are invited to write a Teshuva showing why they are entitled to disagree with Chazal as well as all the Poskim.
