Thanks for the opportunity.
As, I understood A-y he was saying that we have no right to an opinion if the Gedolim have one. Note: this discussion isnt about practice or acting on said opinion against the gedolim, but rather on just having an opinion. As he put it, it is wrong “For laymen to comment on the opinions of the gedolei Torah” and if one does “it isn’t worth very much.” To which I provided a passuk indicating that a LAymen should speak up and voice an opinion, and that in fact it can be quite valuable.
Again, note if Moshe Rabbinu had told Yisro, no my way is better I have my reasons etc. My point STILL stands since my point is laypeople are allowed to have (and voice) their own opinions.
Is it exactly the same? Of course not! (obviously Yisro wasnt on an online forum and he spoke to Moshe directly) but I believe it is comparable.
(As for the other thread perhaps we have different interpretations of “mareh makom” or different understanding of what the OP was looking for. I understood him as wanting to prepare a shiur on the topic from scracth beginning with pesukim, Gemaras, Rishonim achronim and ending with contemprary sh”ut on the subject. So I provided a passuk that comes to mind regarding the subject as a starting point. PErhaps I misunderstood what he was looking for)
