To me, the term "cultural appropriation" refers to things like schools having kids make chicken feather "headdresses" to "celebrate" Native American Day, or wearing a religious symbol in a disrespectful way. Even though people like the person in the post can be annoying, I think it's still progress that we're able to have these discussions, and I think it's too bad that for many people the takeaway seems to be "cultural appropriation is never problematic." I'd take the person from the post any day over someone who thinks they're immune from criticism when they unintentionally engage in behavior that truly is disrespectful.
