No, the presentation is not mostly valid. It purports to discuss disparities in intellect and preferences between men and women in high-energy physics, but digresses into the fact that men die in battle more often than women, that sexual harassment concerns are overblown, that it was unfair that he was passed over for a job when a (named) "less qualified" woman was accepted, that discrimination generally works out in favor of women since men are more likely to die on the job, that Matt Taylor was unfairly dragged for appearing on camera in a shirt covered in pin-up girls, that charges of homophobia at CERN are false, and that all this is due to "thoughtcrime" by the Cultural Marxist Minister of Truth (his words). He even cites that laughable Ted Hill paper.
