Would They Die for a Lie?

[Angrboda]

Secondary sources and primary sources often contain different information. You can't always simply say primary sources are preferred as if you were making an apples to apples comparison when in fact it often is not, but as in this case is an apples to oranges comparison. If a source is guilty of speculation, then document that fact. Implying that a secondary source is only speculating or is guilty of speculation simply because it is a secondary source is not a justified conclusion.

(And I'll also note that you go beyond what you can demonstrate with your primary source to engage in speculation of your own, in spite of having just chastised someone for quoting a source which you feel was engaged in speculation.)
