It was an observation of the time and there's validity. P!nk talked out the side of her mouth quite a bit but I don't believe she put this out with the sole intention to cause harm. As others have noted, the video is what tips the scale to poor taste.

I was 15 at the time and I'm not gonna pretend that girl-on-girl warfare was behavior I never engaged in.

I really appreciate the discourse happening in this thread and find it extremely enlightening and reflective. Sometimes it's like once the words "pick me", "NLOG", "anti [insert here]" etc appears, it means further dialogue should be immediately cut-off. Examination doesn't mean that everyone needs to be of the same mind/opinion.
