well as i said (postulating, not knowing here), it is not usually overt, but imo that usually is another symptom, along with the argument against free will. That usually comes along next, and i can even show you many examples.
I am not sure who this "we" is that you speak for, but i suggest that this is another symptom; including yourself or others in some undefined group--or worse, defined--when you cannot verify membership in this group for anyone, at least imo.
Who is "we?" Because, see, you start out by saying that you do not know, but then you say "We," which infers that you must know. How can their be a "We" that you (and Hitler, and me) have included ourselves in, if we do not know? See, "we" do not even think about this, this "we" that we assume to lend credence to our position, that does not exist.
Of course this is a rhetorical question, my "we" is different than your "we," but i hope you see the point. And when "predestination" is the answer for "what must i do to be saved?" or even "do i have free will" then the same thing is going on. Personal responsibility is being abdicated so that "we" do not have any role in manifesting the kingdom on earth, when you know for a fact that i can also make a case that God does nothing in our domain without human action, and i can even make a case that He cannot.
And i have other, even more overt examples, but essentially by "we" you mean Calvinists, or something similar, amounting to "we, who have been predestined."
