This. Not saying she's guilty because she probably didn't even know him but a confederate flag isn't "fashion".
The kiss and the head shave wouldn't be "problematic". Maybe to few deluded white SJWs on Tumblr but that's it. There's no such thing as "apropriating lesbian culture".
The snake was already problematic back in the day, just not as much as it would be today:
So were the Circus animals. The gun violence in Criminal was also controversial back in 2011. Even politicians talked about it. It shouldn't have been that big of a deal, in my opinion. The Perfume one was definetly problematic because of the association with the Virginia Tech shooting. Thank God they scrapped it. Shame the replacement was so bad.
The kimonos are debatable. If she did it purely for fashion without respect for the culture, then it is cultural appropriation. But, according to some Asian lady who met her when she wore one back in the ITZ era, she was very respectful.
Overall, she's not as problematic as many other pop stars. Queen.
