Just to add to what I've already said, what about Bards, Sorcerers and Wilders (and members of similar classes)?
If someone could honestly say with conviction that the effects of a high Charisma score on spells and/or psionic powers are in any way reflective of that stat's covering physical attractiveness (and apparently the stat does cover that)...I would be...surprised. So then, I assume that for many people, there must be a divorcing of the two lopsided areas the stat covers (physical and psychological).
In accordance with the view that Charisma does cover physical beauty, not a single Bard, Sorcerer or Wilder who is capable of casting/manifesting anything at all, can possibly be ugly.
