Grimes denounces Nazism after ex Elon Musk's controversial one-armed gesture went viral. She responded to a fan in a lengthy social media post following the tech billionaire's appearance at President Donald Trump's inauguration festivities.

The Roman salute is conditionally allowed in Italy and outright banned in Germany. German chancellor Olaf Scholz responded to Musk's gesture by saying, "We have the freedom of speech in Europe and in Germany," he said, "what we do not accept is if this is supporting extreme right positions."
