One of the things that can come up when people claim to be doing things on grounds of verisimilitude is that they're often, shall we say, pretty selective about what bothers them and what doesn't, and the particulars can be a very bad look.
That doesn't mean there can't be some legitimate issues there that are not sexist or otherwise super-questionable in intent; a lot of people are more sensitive to social dissonance than they are to physical dissonance in games (in other words, things that ring false socially or psychologically will bother them more than magic or super-science, or even some genre conventions). That said, when your sense of verisimilitude slams up against things that actively bother someone else, you should at least step back and see if that's a worthwhile tradeoff, and what it says that it is.
(in the specific case of EGG and some other old-school grogs, I suspect they just didn't give a single damn.)
