Studies have shown there is no single determinant of sex, gender, or sexuality. In terms of both sex (genetic) and gender (a social construct), a binary distinction of “male or female” fails to describe a wide range of humans in practice. Meanwhile, sexuality (a preference) eludes any simple categorization as well. Simply put, despite some binary aspects (for example a person either has a Y gene or they don’t), Gender, Sex, and Sexuality are all non-binary and each is instead a complex spectrum… and we can prove it with science and logic.
The bed of nails principle states that while laying on one nail is enough to puncture a person’s skin, laying on many distributed nails isn’t.
