According to an opinion piece in the Wall Street Journal:
Title IX is a simple anti-discrimination mandate that prohibits federally funded educational institutions from discriminating “on the basis of sex.” Yet, without congressional authorization or other constitutional authority, the Biden administration is writing new Title IX rules to socially engineer every aspect of the educational experience—from student speech and school athletics to high-school locker room use and relationships between adult college students . . .
In perhaps the most sweeping change to federal law ever enacted by unelected bureaucrats, the administration’s draft rules redefine “sex” to include “gender” and “gender identity.” This would require every educational institution that receives federal money to allow biological men into women’s locker rooms, sororities and other previously female-only spaces . . .
The Biden rules would also limit the ability of parents to exempt their children from lessons on choosing one’s sex, while empowering schools to transition children without receiving parental consent or even informing parents. Because the new rules both redefine “sex” to mean “gender identity” and carelessly expand the definition of harassment to include protected speech, schools are already punishing children who use biological pronouns to refer to their classmates.
