Atwood suggests that people should study "the science on gender". She gives the impression that she means biology but she would have said "science of sex" if she understood sex and gender. Meanings of words should be important to an author and poet such as Atwood. It's disappointing that words only seem to matter to her when they fit her anti-Trump agenda.
In June 2020, J.K. Rowling tweeted "'People who menstruate.' I'm sure there used to be a word for those people". Later that month, she wrote in her blog, "Moreover, the ‘inclusive’ language that calls female people ‘menstruators’ and ‘people with vulvas’ strikes many women as dehumanising and demeaning."
Today, when asked about Rowling's comments, Atwood said "We can't just throw truth as a category out the window. Is it true or is it not true? That's the first question you should ask about anything. And then, if it's not true, is it fair to say it is? Is it true, is it fair, those are the two big questions you should ask about anything that is put out there for your consideration. I, for instance, do not menstruate. I'm 81. Does that mean I'm not female? No."
I wish Atwood had stopped to follow her own advice: is it true or not true that J.K Rowling claims that old women who do not menstruate are not female? (It's not true).
Atwood might benefit from learning some logic, to help her understand that "only women can menstruate" (true) does not mean the same as "all women menstruate" (false) or "if you don't menstruate at the age of 81 then you are not female" (false) even though she seems to want these phrases to have the same meaning, so she can use them to ridicule supporters of women's rights.
I also wish Atwood had then stopped to again follow her own advice: if it's not true, is it fair to say that it is true? So, is it fair of Atwood to imply that Rowling thinks that post-menopausal women are not female? (I think Atwood is being unfair to Rowling).
Atwood seems to have various theories about words and truth, but she seems to have an extraordinary amount of difficulty practising what she preaches.
