You're either one or the other, plus a mental/developmental/etc disorder or "alternative/unconventional" personality (i.e. a "feminine man" or whatever...). You can't just "feel like" a certain gender when nowadays the left has abstracted the concept of gender so far that it's been rendered undefined. This guy explains it perfectly.
Hope this helps you understand.
With all respect but we don't need that here. I'm not even sure if the person that speaks in that video has any scientific background but considering he is talking about "debunking transgenderism", (as if transgender people wouldn't exist, right?) I don't think his words mean anything in this debate. I am transgender and I got diagnosed with the F.64.0 three times already by different psychiatrists. Psychiatrists with an expertise in this field and they evaluate you as a person with all the symptoms in a very skeptical manner.
As for scientific evidence, uhm - here.
Brain activity and structure in transgender adolescents more closely resembles the typical activation patterns of their desired gender, according to new research. The findings suggest that differences in brain function may occur early in development and that brain imaging may be a useful tool...

Transgender people have a brain structure that resembles that of their desired gender. So in other words: Transwomen are women, neurologically speaking. Therefore they are at least partly also biological woman. That's the scientific stance in 2019. The brain structure, together with psychological factors is the fundamental of our gender identity. Studies like that were replicated over and over again in the last few years. This is not(!) controversial anymore. And all major health organizations on the planet agree with these studies:
The World Health Organization,
the American Medical Association,
the American Psychiatric Association,
the American College of Physicians,
the American Academy of Pediatrics,
the American Academy of Family Physicians,
the Association of Social Workers,
the Royal College of Psychiatrists
and the National Health Service.
They all released statements about transgender people over the last few years, in support of them. So whatever you believe to know about transgender people, it's probably wrong. Literally the entire scientific community of the free world with all the scientific evidence that came out in the last few years disagrees with you. I hope you do some unbiased research and re-think your opinion. I'm sorry I had to bring this up in this thread but I can't possibly let a video like this left unchecked, especially if it's from a very unscientific source.
