Nor the intelligence to actually "mole".
Uh huh.
It's easier for us to imitate them, than it is for them to imitate us.
Which of course makes a mole, someone who blends in.
I think for us it's easier because moling requires a flexibility of the mind, an exercise of the wits, a quick reaction to unanticipated happenings, and the ability to keep one's mouth shut at the right times.
A primitive of course has none of that, possessing a rigid mind, no wits, no ability to cope with the unexpected, and no talent at keeping his mouth shut.
I've been around a long time; while I've seen shitloads of trolls--those who register only to disrupt--from Skins's island, I've never once seen a successful mole--those who register to blend in--if even a mole at all.
They just can't do it.
