Digging deeper there is the connection. This was the main symbol they used when they did use the fist. It didn't have a lightning bolt:
They used a billion symbols. Here's a few more common ones:
These were their primary symbols abroad that would have been available in Canada in 1988 (also places like the USA and Australia):
Nevertheless, the "White Noise Club" used that specific symbol on their newsletter (in the UK) and on banners for local shows during the period:
I couldn't find anything about that interview where he wore the Skrewdriver shirt other than it took place in Japan in 2004,
way later, long after he had left the punk scene, and the shirt looks brand new. At that point it is counterculture kitsch; the sort of thing sold in hipster shops with a sense of irony considering the band's historical distinctions. That's a punk tradition, but one even most punk kids would eschew presently.
Just below that fist, on his arm, which doesn't accompany any other noticeable skinhead tattoos or symbolism, he has a tattoo that asks, "Aren't Thou Bored?" because there is a YouTube video of a cartoon Macho Man Randy Savage saying it, though he actually said, "Art Thou Bored?" He also has one that says, "Tofu", because he says he was into vegetarianism. It's difficult to take his skin art seriously:
Nevertheless, there is a troubling confluence of symbols. Inside the circle are Chinese characters that say "Power" and "Force", which taken together, mean "Authority". The Arabic characters in the red say-- according to Gavin-- "Arm Your Desires" with the AK-47 between them. He jokes this was before Islamic terrorism was a huge threat. Perhaps, but taken in conjunction with the White Noise Club symbol one can easily interpret a synergy of signs:
Arm Your Desires --> White Power --> Authority --> AK-47 (Force of Violence) = Apply the Force of Violence to Establish White Authority
That is set against the same red used by the Nazis which was recycled by Blood & Honour when they took the symbol from the flag of the Afrikaaners, and using color associated with the National Front movement was encouraged by skinheads in that punk scene:
It is a troubling tattoo.
Race purists who insist on using violence to avoid mixture of cultures and bloodlines don't tend to willfully and openly commit this with their namesake bloodline.
No, I'm afraid his marriage is a mutually exclusive act to this ideology. This isn't a surreptitious tryst with a slave.
