One of Avi Weiss’s main issues is that he denies the concept of Gedolei Hador.
Well, I should hope he does. If he doesn’t respect the gedolim of 1000 years ago, it would be pretty weird for him to respect the gedolim today.
His religion is literally ??? ???? ?????? ????. And if there is a conflict with halacha or hashkafa, you just say that today it is different. And if there is a conflict with today’s poskim, you just say “I’m also a rabbi”.
And since he ordains am haaratzim, anyone is a rabbi.
