There are an infinity of genders, in principle, and if you say no, then expect to be smashed:

“A Scottish 17-year-old who was suspended for filming his teacher telling him that he could not say in class that there are only two genders has been told he cannot return to his school. The Aberdeenshire pupil, named Murray, had shared the video to social media because, according to a friend, he wanted to expose the left-progressive, anti-scientific ideologies being taught at Scottish schools, and expressed concern that telling very young children that “boys are girls and girls are boys” is “a very dangerous thing”. The viral footage revealed that the teen had been removed from class for stating that there are only two genders, with the teacher telling him that whilst the boy was entitled to his “opinion”, he could not share it at school because “the authority” and school policy dictated that there are many genders and to assert otherwise was “not acceptable” and tantamount to discrimination. “I know what you think, and I know what the authority thinks, I know the authority’s point of view is very clear,” the teacher is heard saying. Murray had been suspended for one week, according to the school on grounds of sharing the footage of his teacher without his consent, later tripled to three weeks. Now, the pupil has been told that he will not be able to return to Mearns Academy to finish his education, the Evening Standard reports.”
Clearly, he is better off seeking a new school of home schooling, or just learning himself, working on STEM topics, then sitting the exams. That would be the better course of most White male students, as the conventional high school is a toxic environment for them.
