I'm gonna give a bit of leeway on this, because what if your character really does have a very strict sense of honor, than it would sort of fit. Prejudice is personal choice, because your character could go into the game hating one archetype for any reason, aesthetics would be a big one! So I'm not really banning you from spending points in personality qualities, but put thought into it. If you're "Real world" persona isn't a smooth talker, they're not going to be a smooth talker in game, and that's just a realistic limit.
I'm allowing players to create characters that used to be beta testers, the level of proficiency is up you.
