Not sure how the parent would respond, but early on, while discussing Rosalind Franklin's DNA diffraction findings, he makes an unnecessary comment about the Nobel prize going to "the two white men." It seemed out of place compared to the rest of his talk.

I didn't feel like the talk gave off an overtly political tone.

The New England Journal of Medicine on the other hand...cancelled my subscription due to how political it has become. Still has very good review articles, though.
