I didn’t call any gedolim disingenuous. I’m skeptical that a gadol would sign on something which he considered untrue. Even if the person you spoke to was a gadol, and even if he did tell you it was nonsense, maybe he didn’t really think so, but felt there was no harm in telling that to you.
I wasn’t appealing to authority; read my comment in context.
I have news for you though. We Jews believe in appeal to authority.
