Even the popular connotation of the strawhats is that they like to go in and revolutionize the government in exchange for a good meal. Even the Robin-centric arc they shoot down the world government flag. Oda literally approves the casting calls. As mentioned previously Oda said she’d be Russian. You don’t even need to delve into the dramatic irony mentioned in the Twitter replies where Franky told Robin that it’s not a crime to exist. You don’t even need to draw a real life parallel to the demonization of Robin from the time she was a child. You needn’t concern yourself with the kanji for kaizoku/pirate being “sea thief” (海賊) which gives everyone Luffy meets pause and how you would certainly be one of those people who hates him because of it (and the valid reasons for being that way because that would require theory of mind).

I’m saying that even if you had the most shallow understanding of Robin that wasn’t even informed by your own reading of the text, you would have come to find that Robin doesn’t fit into your mold of what a good guy looks like and this would be a silly thing to post. They are drawn to characterize chaotic good the same way bobo and kiki are designed to be round and pointy respectively.
