I'm still trying to understand why the billboard was offensive. I do unstand that it was meant to provoke a reaction, but I don't understand why it would get a reaction or be offensive.
The poster said woman = adult human female.
As I understand it from a pp, this is offensive as it excludes trans-women who are women as well.
For the poster to exclude trans women, it must be because they are not female.
Can we therefore not use women to now mean adult human females and males who identify as women?
And then for areas of life which need sex segregation, such as sports, medicine, intimate care and changing facilities, can we not use the term female instead of woman?
If trans-women say they are females, then I don't understand how saying woman= adult human female would be offensive as it wouldn't exclude them.
Incidentally, what are the OED definitions of sex, gender, trans woman answer man?
(I have asked this question in the other Ocardo thread and earlier in this one and haven't had an answer, so apologies for posting again but I really want to know/understand)
