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?)
