OMG, this is unbelievable. After spending days insisting that the definition of the word woman is not a human being who is adult and female, but rather that the word woman is defined in the peculiar way you personally have decided and decreed it to be defined, you say

I can't choose how words are defined.

Then in true Humpty Dumpty style, in practically the next breath you turn around and say

anyone who considers themself a woman is a woman in my book, as I have also repeatedly said.

Obviously, when you use the phrase "in my book," you must be referring to a niche title of recent vintage such as The Big Book of Gender Woo; Golden Book's Guide to Gender Gibberish; or The Front Hole Monologues (aka Andrea Long Chu's vile Females), not to any estimable, time-honored tome like Dr Johnson's landmark lexicon of the English language, or any other reputable dictionary of English such as the OED or other dictionaries published under the Oxford imprint.
