So I'm not a total raging feminist who gets offended at every little thing, but I do have to say that it really bugs me when people talk about my doctor and say "he." It usually happens when I'm filling prescriptions, and actually the first few times it legitimately confused me because I assumed they must be talking about someone else, like maybe the pharmacist who filled my prescription. Not that I think all pharmacists are men, but I don't usually connect an out-of-context "he" with my female doctor.
I think that people just need to adjust to saying, "Your doctor stated that your son should take this twice a day," rather than "He said your son should take this twice a day."
(But just as a guilty admission, I always talk to people about their male printer. Like, "If your printer has any questions about this file or any problems at all, he can contact me directly by phone or email." I know I need to fix this.)
