In principle that's the case in Germany, too, but only if the person is of public interest (otherwise you're not supposed to publish any pictures of them where they are the focus of the image) and, secondly, it has to serve actually discernible satire, commentary, etc. Merely saying "I'm an artist and that's art" doesn't fly, hire a model. Similar to how you can dish out a hell a lot of insults when you're doing a pointed critique, but if the critique is missing and it's only abuse that doesn't fly.

Ha. Idea: An AfD politician as a garden gnome peeing into the Bundestag.
