The man gave both his name and his qualifications. The qualifications indicate to me that he is a high-level medical professional who must be speaking with above average knowledge (even for a medical profession). He explained that he is involved in COVID testing and said that the vulnerable should be protected.Therefore he agrees there is a nasty illness out there but the reaction to it has been extreme. He said it is politics playing medicine.
If he is a crack pot what other things has he been involved in that show this? His name is in the YouTube. He is not hiding.
The principle in this scripture can be rolled out to assess medical professionals at all levels.
(Matthew 7:16) . . .By their fruits you will recognize them. Never do people gather grapes from thorns or figs from thistles, do they?
