I feel the point was pretty clear, but I'll sum it up for you.
The point is this: If you want to say that other people are roleplaying wrong by not applying their low Int score to all of the listed facets of the Int attribute (like Max very clearly is saying), and you want to claim that you absolutely have to apply it to all of those facets with no exceptions in order to be following the rules (again, as Max has very clearly said), then you don't get to selectively apply your high Int score without hypocritically violating your own statements. Calling it a "quirk" doesn't negate that. To paraphrase you, "it seems an awful lot like someone's bending over backwards so they don't have to roleplay their ability scores."
Ooh you got me there, I was trying trying my damnedest to not have to play a high mental ability score.
