There's a genre of person that is like genuinely offended if you show them artwork of people who don't match their myopic beauty standards. And because they think its icky and their default state is looking at pictures that make them horny, they assume the only possible reason you could be drawing people like that is if its a fetish
Also worth noting that fetishes are entangled with people's non-sexual interests. This is normal brain stuff. Using it as a way to imply someone is duplicitous for drawing their interests because they may find some of that cloud of concepts sexy sometimes is asinine. Also so crazy how it's only duplicitous to do this if you are queer or have non-normative sexual interests. Het guys with an extreme bias for drawing/writing a single female body type and personality in their fiction seem to generally be off the hook for sneaking in wank material. How curious.
