You are arguing that he came to the "wrong" conclusions without actually arguing against those conclusions, or how he got to them. Instead, you are arguing that a reasonable person can come to your conclusions, and therefore Benn is not a reasonable person.

At no point in his video does Benn claim to be representing the consensus. The whole premise of his videos is that he is introducing something for which there is very little consensus! Each paper has its own conclusions, which don't have to be the same as Benn's. This whole thing boils down to an attack on Benn's character ability to draw meaningful conclusions on his own.
