The question "who started it" is beside the point. It's nothing but a variation on "what about ...?", in other words, an attempt to change the subject. My all-time favorite was the contribution of some participant in a panel on a question of the U.S. intervening in some current humanitarian disaster or another (Myanmar and the Rohingas?): "What about the U.S. overthrow of the native Hawaiian monarchy?" What is really weird is that you need a couple years of law school or a Jesuit education to understand some cancellations. It took me some time to figure out why JK Rowling was cancelled for suggesting that the word "women" (two syllables) was an acceptable substitute for the awkward phrase "people who menstruate" (six syllables). Strunk and White would certainly approve, but I finally got it. Men who believe they are really, spiritually women must be considered as identical to and interchangeable with those conventionally considered as women. Since such individuals, erroneously assigned male identity at birth on the basis of objective and reliable evidence, don't menstruate, Rowling's suggestion must be regarded with contempt as showing a less than approving view if not hatred of a contestant in the Victim Olympics with a very high intersectionality score.
