I don't understand why you immediately post some extreme example. These are always rare. That S. Carolina miss is apparently a bit off, but all in all, it's not her fault and she is an extreme example. Anyway, most misses and misters are far from anything like that. E.G. most Czech miss candidates are high school students with knowledge of foreign languages etc etc. I just don't get that attitude.
But whether it applies to specific group of people or not (it of course doesn't, that's only your hard coded stereotype), have you ever noticed how happy people that "don't think much" are? There is a reason for this.
Whatever the way it is, Miss and Mister is not about intelligence, just about looks. Like any other competition, be it soccer with ability to perfectly drive the ball nad combination of gameplay, F1 for mastering approaches to turns or Thai-Box with combination of proper kicks and punches or .....fill the blank.
Whatever J. Karas does in his personal life is not my concern, he HAS LOOKS, that's what counts regarding the Mr. World competition.
Rhetorical question, of course you do.
