An employer who fires an individual for being homosexual or transgender fires that person for traits or actions it would not have questioned in members of a different sex. Sex plays a necessary and undisguisable role in the decision, exactly what Title VII forbids.
What the article falsely alleges:
six Supreme Court justices just decided that what the Southern racist really meant by “sex” was gay and transgender [...] The Gorsuch decision in Bostock v. Clayton County, Georgia find[s] that “sex” in Title VII covers any group having anything to do with sex
Cherry picking .
In Hosanna‐Tabor Church v. EEOC (2012), the government sued a church school that fired a teacher for violating one of its religious tenets. The court ruled that punishing a church for not retaining an unwanted teacher violates the First Amendment.
The court case above was a 9-0 rebuke of the Obama administration.
