Mass deportations don’t keep out ‘bad genes’ − they use scientific racism to justify biased immigration policies

  Threats of mass deportations loom on the post-2024 election horizon. Some supporters claim these will protect the country from immigrants who bring “bad genes” into America. But this is a misguided use of the language of science to give a sheen of legitimacy to unscientific claims.

  Politicians invoke genetics to confirm false stereotypes that immigrants are more violent than native-born citizens as a result of biological differences. This is despite the fact that immigrants living in the country with or without legal authorization have significantly lower crime and violent crime rates than U.S. citizens. Moreover, there is no strong genetic evidence to support a biological predisposition for committing violent acts.

Genetic paparazzi are right around the corner, and courts aren’t ready to confront the legal quagmire of DNA theft

  Every so often stories of genetic theft, or extreme precautions taken to avoid it, make headline news. So it was with a picture of French President Emmanuel Macron and Russian President Vladimir Putin sitting at opposite ends of a very long table after Macron declined to take a Russian PCR COVID-19 test. Many speculated that Macron refused due to security concerns that the Russians would take and use his DNA for nefarious purposes. German Chancellor Olaf Scholz similarly refused to take a Russian PCR COVID-19 test.

  While these concerns may seem relatively new, pop star celebrity Madonna has been raising alarm bells about the potential for nonconsensual, surreptitious collection and testing of DNA for over a decade. She has hired cleaning crews to sterilize her dressing rooms after concerts and requires her own new toilet seats at each stop of her tours.

Stop calling it a choice: Biological factors drive homosexuality

  Across cultures, 2% to 10% of people report having same-sex relations. In the U.S., 1% to 2.2% of women and men, respectively, identify as gay. Despite these numbers, many people still consider homosexual behavior to be an anomalous choice. However, biologists have documented homosexual behavior in more than 450 species, arguing that same-sex behavior is not an unnatural choice, and may, in fact, play a vital role within populations.

  In a recent issue of Science magazine, geneticist Andrea Ganna at the Broad Institute of MIT and Harvard, and colleagues, describe the largest survey to date for genes associated with same-sex behavior. By analyzing the DNA of nearly half a million people from the U.S. and the U.K., they concluded that genes account for between 8% and 25% of same-sex behavior.
