This forum uses it in a bizarre way I'd never seen before... I always thought of it as exactly what it stands for:
White (obvious enough)
Anglo Saxon (English/German/Northern European with fair features)
Protestant (mainline denomination, not evangelical).
I've heard that definition a lot, but
1. In which way are Germans and Northern Europeans Anglo Saxons?
2. Isn't Anglo Saxon almost redundant in this case, because how many White Protestants are there historically that are not British, German, Dutch or Northern European? (Huguenots? Hussites? Valdesi? Sobozinians?)
Excuse my ignorance and preliminary knowledge on the subject, but I was under the impression that the Anglos were from England and the Saxons were from Germany, giving rise to the definition I used. As for your second point, I agree. I was just saying I'd usually heard it used that way. Honestly, without trying to veer off subject or getting to tender subjects, I kind of always associated it with ethnicities of people that the Nazis would have gone all googly-eyes over.
