This isn't so much of SJW art extremes so much as more of someone generally being a jackass over drawings they don't like that one may see it as "SJW" and it is a week old but I'm somewhat surprised some minor drama from Twitter got some mention here:
Some Twitter artist makes a tweet and a drawing in reference to how drawing one body type gets bitched at but the other gets thirst from that same crowd, cue some people acting like idiots because of a body shape.
One believes this has to be sexism because of the body shape.
Others go on how one is realistic and the other isn't even though technically, one could exist albeit without exaggerations from within the drawing. I'm just more convinced though these guys got somewhat miffed over a drawing that they think there's some point they got just because they say they see women IRL or how they believe one is totally a sex object when that can be seen differently by others.
Also found one other tweet that likely referenced this when I came across some circlejerk going on about "gamers won't like this more realistic body" which I can only imagine may be a response to TLOU 2 memes over Abby having a body of a guy in one screenshot.
Side-note: one of the tweets above also tried to make a video over the artist he complained at.
His video rant went so well for him that he had to make another one where he tries to address the criticism he got. I'll admit to not watching the videos but then again, the videos sound like they'd be less of a constructive critique and just more of something where he'd bitch about shit he doesn't like a la the Quartering or whatever left-wing coutnerpart Quarterpounder has.
