From further down in the article:

Pink wrote that she was not trying to get any artist fired or silence anyone but that she took issue with Macklemore’s putting “violent images” of Israel’s military campaign in Gaza up in a stadium filled with families, then telling Jews in the audience that “it wasn’t about them.”

She's mad that Macklemore put up pictures of the shit that the Israeli military did? But she takes no issue with what the military itself did?
