More like a defect in recall, since if there is a basis for it, I'm sure I've

You claim to be good at research so figure it out. Try to actually learn
something for once. It'll do you good to admit ignorance and correct the

Given what I usually read here and how unreliable it tends to be, I'll just
assume that it's baseless unless you can provide some sort of reference.
