Okay, fine. So let’s go with the argument that ignorance is an excuse for appropriating the symbols and bodies of people from another culture—people who, notably, suffered monstrous persecution at the hands of the people from the culture you identify with. Let’s say that somehow having so little interest in or concern for the people you are trying to depict that you get your depictions all wrong, OFFENSIVELY wrong, makes you a decent person and not racist at all.
Now that people have taken the time to explain to you what those symbols mean, why they feel your use of their cultural symbols are inappropriate or offensive—even though this is absolutely something you should have decided to educate yourself about BEFORE if you had any respect for them at all—would you please just go, “Okay, that makes sense. I see that what I/someone else did was inadvertently offensive. I’ve made a note, and in an effort to be more respectful toward you and your culture, I will be more careful about how I use these symbols, and I will do that by educating myself about them and not using them as my personal fashion statements.”
When you sit there and shriek, “IT’S NOT EVER RACIST TO DO THIS! IT’S COOL! WHY ARE YOU BEING SO SENSITIVE!” that’s when you go from being inadvertently racist and offensive to knowingly racist and offensive and callously not caring about who you hurt as long as you get to keep whatever it is you’re doing for the morally vacant reasoning of “it’s cool.”
