White supremacists that collect viking trappings are pathetic, historically moronic little folk.
I keep saying it. Vikings are the second worst historical crew to emulate if some vague idea of whiteness is the goal. My ancestors stuck it in anything with a pulse between Baghdad and Killearny, for fuck's sake. They dicked their way across so much of Ireland that modern geneticists have no idea who were redheads first. About the only worse choice you could make is the Mongols, thanks to Genghis fucked-my-way-into-a-quarter-of-the-world-population Khan.
That said, it ain't a challenge.
It's what's called a declaration of faith.
And there's three big reasons to make a declaration of faith.
One is to honestly and exuberantly proclaim your belief.
Two is to let the preacher know you haven't been bobbing for cock during the sermon even though you've been hanging out in the pews in the back and not doing much.
Three is to take a good look at the rest of the congregation and see if there are any sinners that need a righteous castigation, which the faithful are all too ready to provide.
Decide among yourselves which is what. And take care of yourselves out there.
