I think I see what you're going for. Anita doesn't act like a real-world guy, she acts like a stereotype of a guy. Which I'd be fine with on its own, but combined with the fact that anything remotely feminine is treated as bad, and the treatment of most of the non-Anita female characters, it feels very misogynist. Like, the only reason Anita is a "good" woman is because she rejects everything vaguely feminine (I mean, I'm not sure she even cleaned her own apartment back when she live alone, for fuck's sake).

(Full disclosure: I have not read any of LKH's books first-hand, nor do I intend to, because I think my brain would melt. Also, I am hetero-, cis- member of the Has A Y-Chromosome Club.)
