It’s sad that HN deletes the original comment so I can’t see what this is in response to, though I see the doctor’s name in your links. Going to watch the original and then read your links. Even though this “doctor” is probably a whack job, I love listening to people I disagree with and seeing their points rebutted.

If you click on your username in the upper right hand corner, there should be a "showdead:" option that you can set to "yes" in order to see these posts.
