The Exulansic channel had screenshot / discussion posts for days about that cartoon. I think the people who commissioned it to have a laugh and share it among Sierra's TRA critics got their chuckles, then when Sierra launched a criticism campaign in return (justified or not, the discussion posts were retaliatory, she was hobbyhorsing it) all those TRA critics jumped all over it and called it a bullying / harassment campaign. They could point to several posts of hers that are off her usual topic, targeting an artist for an unflattering picture.
Sierra's strong suit is arguing science against liars. She was tricked into debating morality (racial caricature) with morons, liars and play-dumb opponents / trolls. Because the lies are built into the social "sciences", the liars can counter her arguments with clever sophistry and rehearsed arguments, and these are authoritative in their disciplines. We may recognize them as bullshit but they carry weight to YouTube mods. Sierra was tricked into their strong suit, and she discovered how conservative sociologists feel when they try to bring actual science and data into discussions about race, culture or feminism. The real science doesn't count there like it does in countering TRAs, because people will fight to protect their kids, but they'll shy away from conclusions that sound racist, and choose politically correct lies.
