Some hours later: I finished re-reading Intersex. These books and others I've read have a lot about how insistent on a gender binary the doctors and mainstream U.S., British and Canadian culture were (and are). There were theories about how if doctors operated on intersexed children less than two years old, they could be raised in the gender assigned them and not want to change. Infants with XY chromosomes who didn't have what doctors considered adequate penises were assigned female and operated on accordingly. Children with XX chromosomes and clitorises deemed too large had the clitoris removed or reduced in size. Those were a couple of the things that commonly happened. As of 2007, there was still a notable amount of surgery. Among the conclusions in the books I've read were to wait until the intersexed person hirself could consent to surgery, if ze wanted it.
There's a lot of biological essentialism, too, from some opponents of surgery like that on infants as well as proponents of it. I was more of an essentialist than I am now. I certainly think that hormones can produce considerable changes in a body. Clearly there's much more to it than chromosomes and hormones. Much smarter people than me have tried to figure it out.
Later: I went to Best Buy and got Dad a gift certificate.
Later than that: Mom and I went to a new grocery store that opened in the shopping area near us. I should have remembered that Mom would set a painfully slow pace, as she wanted to look at the price of every item. Fortunately it wasn't a very big store. I got red velvet cake, which I didn't need but which was on sale. It has quite a different taste from red velvet whoopie pies.
I worked on an editing job.
