“I was discussing the topic of menstruation during a class recently and was called out by one of the pupils who now identifies as a boy for failing to say that boys can have periods too,”
The correct answer is “Don’t be ridiculous. No, they cannot.”
Why are they discussing menstruation at all?
Ah, proper terminology - a male-boy or a male-man can never ever menstruate. Remind them they may covet masculinity (boy/man) and femininity (girl/woman), and want/desire to convert themselves into the opposite of what they were blessed to be born. But each will always be truly be what they were born, either male-XY or female-XX. Nature (& God) knows what we truly are. Some males are feminine and some females are masculine, yet each is still the XY or XX because their dna does not lie.
