Fans at a recent right-wing extremist rock festival in Germany thought they were getting free T-shirts that reflected their nationalistic worldview. But after the garment's first wash they discovered otherwise. The original image rinsed away to reveal a hidden message from an activist group.
With a skull-and-crossbones logo and the message "Hardcore Rebels - National and Free," some 250 black T-shirts given away at a recent right-wing extremist rock festival were quickly snapped up. But there was more to the tough-looking image than met the eye.
Once the rightist rockers washed their new shirts, they were dismayed to find an entirely different message: "If your T-shirt can do it, so can you. We'll help to free you from right-wing extremism." The offer, complete with contact information, came from a group called Exit Deutschland, which helps people get out of the neo-Nazi scene.
The group sent their "Trojan T-shirts," disguised as a donation from an anonymous party supporter, to the organizers of the Aug. 6 event, which took place in the Thuringian city of Gera and was sponsored by the right-wing extremist NPD party. Exit Deutschland has been pleased with discussion the initiative prompted in online neo-Nazi forums, co-founder Bernd Wagner told daily Süddeutsche Zeitung on Wednesday
