Not a geneticist here but I’ve taken a class on the subject, so while not an expert but can get my way around conversations.
I first noticed the divergence from true science in relationship to genetics when scientific American published an article claiming race was an illusion. They used quite a bit of technical terms but at the end I thought it was a farce and PC hogwash.
How can anyone deny the existence of race in humans while acknowledging the legitimacy of animal husbandry and developing breeds, a process used for thousands of years? I mean would these same scientists say there was no difference in a Great Dane and a Rat Terrier or a Leghorn Hen and a Buff Orpington?
Another turning point in my mind was the shameful treatment of the great James Watson who was forced out of his University position after daring to speculate there might be a connection between race and inherent IQ potential.
(As a reminder Watson was the co-scientist with Crick who discovered the Structure of the DNA molecule. Basically one of the most important scientific discoveries of all time)
True science is under attack more now than since the days when Galileo Galilei was sentenced to life under house arrest for speculating the Earth was not central to the solar system.
