Also signed into law on Monday was a bill that bans all trans women from playing on girls’ or women’s sports teams at state high schools and colleges. The law, which the ACLU says directly violates the policies of the Idaho High School Activities Association, calls for an examination of the student’s body, testosterone levels, or “genetic makeup” if there is any controversy over their gender. Critics say it sets a dangerous precedent for discrimination against young trans people that could be modeled nationwide.
