Sutcliffe said that the school administration placed him on leave after he congratulated two students, both biological females, for their exceptional work in solving a math problem in class.

He recalled saying, “Well done, girls!” to the two students, but to his dismay, one of them reportedly does not identify as a female.

“And that in her mind was a misgendering,” Sutcliffe told Fox News.
