I rather liked that bit as I identify as asexual myself. Lack of hormones plays a role in making some (a lot of!) people asexual. It almost makes it a shame to admit that she could sort of be right. There are asexual homosensuals or homo-romantic people out there. This doesn't, of course, change the fact that D-Dore's neutering was for sanitization. Boo, Rowling. Booo!
