Using etymology to govern usage is known as the "etymological fallacy." Usage is governed by, you guessed it, use, not the origin of the word. The origin, of course, influences how a word is used in that it provides the starting point, but meanings shift over time, and lexicographers come up with their definitions by surveying how people actually use the words, not by studying the etymology. In other words, it is unreasonable to determine today's usage based on how the language was used a thousand years ago. If it were reasonable, we'd still be using "silly" to mean "blessed, fortunate" and "awful" to mean "inspiring wonder.". . . If people today perceive it as sexist, it is sexist, regardless of how it was used in ages past.
