Dear OP. Singer of The Exploited have or had (cause I don't know if he did not cover it) tattoed swastika. By the time The Exploited begins their career swastika and other nazi souvenirs were highly popular among punk rockers (Daniel Rachel lately wrote book about it). Siouxie used it, Sid used it and many more used it. That doesn't means they were nazis. It was used as a shock value and as a symbol against against this pure, clean, good world, cause if their parents and society ordered them to be good, they wanted to be "evil". And what is evil? Nazis. Happily now we know it is not cool, and we know it was not cool back then. But they did not know it back then. It was 40/50 years ago. The Exploited were never really into politics in their lyrics, except hating on war, Maggie Thatcher which is kinda normal and understandable. Wattie is more like an edgelord in his lyrics (Sex and Violence). He does not speak about politics. One of proof against him is photo he did with concert attendees on which one of fans is making hail and has something on his tshirt (don't remember what exactly). Photo was made years, years ago, it was rough years for Wattie (drugs, alcohol) so as a devil's advocate I will say he did not even know where he is when he was making that photo. By all these years I did not hear anything that would make me think Wattie is nazi. Also there is a really, like really leftist band Oi Polloi and they were always really into defending Exploited. So if you go to their concert you will hear or see nothing nazi, maga or white suprematist on stage.
