A person (usually a white woman) that takes offense on behalf of another group and stands up for them, even though the group involved never asked to be defended or were offended in any way.
Person 1: And here is a picture of me in a Kimono when I went to a wedding in Japan.
Person 2: That is incredibly offensive that you did that. Do you know what cultural appropriation is? You cannot wear the clothing of other cultures.
Person 1: I was actually given this and asked to wear it by my friend. Everyone there was really happy to see me wearing it and I was given a lot of compliments. Emily, you are not Japanese, and haven't even been to Japan, who are you to say that I cant wear this when over a hundred Japanese people expressed joy in me taking part in their culture? What are you, some sort of woke knight?
