Sexuality is a spectrum. Gender may FEEL fluid but baby nobody is naturally changing genders. Even when they do, there are certain aspects of the male and female reproductive system that cannot be changed or imitated. You can put a dog in a duck costume and call it a duck but it’ll still bark at the end of the day. Acknowledging actual science doesn’t make you transphobic. Live the life you wanna live. Be happy. But insinuating that being scholarly makes you transphobic is absurd.
