I think objectification can only happen when a character recieves enough characterisation to not be a random slut but not enough to be able to make educated guesses about which fucked up things she'd agree to.

Scott Marlin's persona can't be objectified because you only ever see her getting dick, nobody gives a fuck about her consent.
Frieren can't be objectified because she's fleshed out enough you'd be able to argue she'd be into that shit given her character.
Cpt.Titjob here, who talks once every three issues, who's mostly known as Dr.Testiculous' girlfriend, and died in 1992 before having an off-screen funeral because nobody gave a shit, can be because you care about what she feels but don't know if she'd spread them for those eight disembodied horse cocks.


but ultimately you shouldn't give a fuck and remember that when these Tumblr/Bluesky hippies harass an artist about this, 9 times out of 10 it was a woman all along and they end up looking retarded.
