Whilst I don't think it's necessarily anyone's place to speculate how others would react in such a situation, I believe clw_uk would listen to the Buddha and believe what was said.
We all have different approaches to trying to piece together for ourselves what the Buddha actually taught... I'm sure no two approaches are entirely the same. No matter how confident that we may be that we understand the Buddha's teachings, we should never be complacent and never think we have a monopoly on their interpretation.
"Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education." - Ven. Thich Nhat Hanh
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
