Okay, some points and questions for trans supporters:
1.) If transwomen were female, then they wouldn't be TRANSwomen, they'd just be women. Being male is a necessary condition for someone to be a transwoman.
2.) Humans cannot change sex. That's a flat fact. You can argue that "gender" is more important and carries more weight than sex does, but you cannot argue that a male literally becomes a female through transition. They become feminised not female.
3.) If a sense of one's self specifically in regards to one's sex is what dictates gender, then; what causes that mechanism biologically? How does that explain trans people without (genital) dysphoria. How does that explain people whose sense of self is based entirely on our current biology and the experiences that causes, and nothing more?
4.) If being trans is based on a sense of self which cannot be externally observed, how do we know who is trans and who is not?
5.) How is it possible to have a sense of self that is not consistent with your material reality, without it being pathological?
6.) Is it worth possibly (probably/definitely) materially negatively affecting all non trans females, in order to validate 0.2% of male people.
