By denying access to women's sports teams Ellison says that the would-be girls are being "bullyed". Kind of the same thing with getting a driver's license before age 16, smoking cigarettes, buying and drinking liquor, etc., all examples of bullying. but are in fact illegal.
"The orders attempt to ban trans children from school sports and define two sexes — male and female — that are “not changeable and are grounded in fundamental and incontrovertible reality.”
Ellison called the Trump administration’s actions “bullying tactics — plain and simple." His position is that he is enforcing the law as it applies in Minnesota
Federal legislation dating back to 1972, Title IX, was meant to gain a measure of equality in men's and women's sports. Schools were required to offer similar sports opportunities to both sexes, in terms of both numbers of participants and financial commitment. It didn't mention boys participating as girls.
