Thanks for the laugh.
It all boils down to this, are you an insider or an outsider? Is a person truly a part of a culture? Have they immersed themselves in it fully? Do they understand it intuitively? Or are they on the outside looking in... just a faker, a poseur, a pretender?
Germanic heathery is a folkway, sure, but there's no reason to assume membership is based solely on ancestry. Why can't a person of worth be adopted/accepted into the tribe? For damn sure, just because your mom ma's from Norway doesn't mean I have to like/accept you! So why should the opposite --- automatic rejection -- be true either? That's best determined a case-by-case basis.
"Only the truth that in life we have spoken.
Only the seed that on earth we have sown.
These will pass onward when we are forgotten.
Only remembered for what we have done."
