Wait...so, going bald is evidence of someone being male (even though hair loss can and does happen to women), but being pregnant and giving birth are no indication at all of being female?
I'm okay with the biology stuff, I get that. I even believe that sex and gender match up in the overwhelming majority. If Jason has been called 'female', I wouldn't have said anything, if someone wants to point out physical characteristics in a way that's offensive to another person, I can't say they're not accurate. 'Fat', 'ugly' and 'bald' are all perfectly accurate, descriptive terms and, for some, they're not negative or offensive. Still, most of us manage not to point out these accurate, physical realities.
Wouldn't it be nice if it was his films we were celebrating rather than the pregnancy?
It would be absolutely bloody lovely but not something you can really hold him responsible for.
