I can’t believe I’m even going to dignify your statement with a response
Even if I grant you #1 (which I wont) these gedolim NEVER told ANY girl to get married later. By taking the words which they DID say (a bracha for one who marries an older girl) and twist them into things which they did not say (getting boys to date ealier and girls to date later) is a crime against these gedolim.
These are people who choose their words very carefully, they say what they say and they don’t say what they don’t say.
Spare me the “Rachel Bitcha Haktana”, and no, I’m not muzzling them, I value them enough to pay careful attention to what they say, you’d be wise to do the same
