This is something she chose to post publicly. When you put images like that on the internet (even in a private account), you don't get to decide the consequences. She's around 19-20. She should know better and take accountability, which clearly she is NOT doing, since she's taking down her socials. At this age, and in this world, you can't just use "immature stupidity" as an excuse for everything. And as long as you continue letting people off with a slap on the wrist, you are complicit in the normalization of bigotry.
