"Bitch" has too often been a sexist code word used to demonize women who dare to show any assertiveness or independence. So an argument that uses that slur three times in a single paragraph is immediately suspect. And given how much ingrained sexism there is in comics fandom, I'm not surprised that there would've been a segment of the fanbase attacking Lois in that way. When Star Trek: Voyager
came along, there was a lot of comparably ugly rhetoric about Captain Janeway.
