Alot of people argue that we cannot be other gender than our 's assigned at birth based on our feelings.
But how does one know they have to behave in a way based on genitals, when I was a kid when I didn't even knew that girls and boys have different reproductive organs, before that
I wanted to be a girl, to be like my mom.
Saying that we can never be female are they mocking the current science? Because just give it time anything can be possible soon we will have IVG then many other new reasearch that may push more towards gender affirming directly or indirectly.
Now after observing I think everyone shares some similar habits and people can choose to be what they want, but people have some superiority complex based on their birth and when it shatters they try to cope by hating.
