Are you suggesting by her slightly lifted leg that she’s somehow mocking the Holocaust victims? Because I simply don’t see it that way. In this one she’s not even showing her face, so it’s not a “look at me!” type of photo anyway. Too much imagination can turn any apple sour.
If taking a selfie in front of thousands of shoes removed from children who were sprayed with acid until their flesh melted from their little bones doesn't offend you, then I am sorry.
