He had permission to paint a number of the walls, and was even commissioned to paint a number of them. His paintings are beautiful, and regardless of whether I understand the language or not, I would rather see his paintings than ugly scrawlings I can understand like "KKK 4eva" etc.
One law for Muslims and another for other people? I don't see you having a cry about the people who did the ugly tagging he was painting over. Seems like you're the one that has one standard for Muslim, and one for others...
Edit-
Did you even watch the video you linked? Or just read the title and use it as an excuse to start spouting your biased hatred for Muslims?
9 seconds to 13 seconds. Ugly scrawls. How do I know they're not Picasso or Rembrandt? Firstly, because I'm not a moron and know they're both dead. Secondly, because I'm not an idiot and know what their art work looks like. Thirdly, because I'm not an idiot and can read what is written in many of the ugly scrawls he's drawn over.
And are you saying it would be OK if it was Picasso or Rembrandt? Because this guy is a brilliant artist commissioned by a lot of people who hold his work in high regard, so if in your opinion it would be OK for esteemed artists to make ugly graffiti on walls without permission, but not OK for this esteemed artist to do graffiti WITH permission, that is a pretty blatant and disgusting discrimination you're making there.
