If a song includes lyrics that you cannot say without being accused of being a rabid racist, you would think that this would be a sign that your White ass should leave it alone.
So she changed the word nigga to ninja and that supposedly makes it alright? Umm fuck no. It's still gross cultural appropriation and seriously who needed to hear this in the first place. I am sick and tired of White people stealing from people of colour. We don't need your take on our culture, our music, or anything else that belongs to us. The entire culture is built around Whiteness and yet that is not enough for them, nope anything that clearly belongs to a culture of colour has to be up for grabs as well. Perry can go and fuck herself.
