In science - especially health science - it is not the responsibility of the skeptic to prove that a particular theory is wrong, rather it is the responsibility of the person making such claims to substantiate them.
The OP walked into a room full of very curious people and called them idiots without any attempt at enlightening them on what statements or assumptions might be wrong. In what way is that helpful? HN is not a peer-reviewed journal, it's a place for discussion and he detracted from that discussion.
Instead, I was hoping he might provide something meaningful that we could consider in trying to process this anecdote.
