[MD] Intellect battles the barbarians

[Arlo Bensinger]

[Platt]
Apparently Arlo can't tell the difference between intellectual, social and 
biological (sexual) values.

[Arlo]
The Muslims tell women they must cover their faces because it is sexually 
provocative for them to appear barefaced.
The Christians tell women they must cover their breasts because it is 
sexually provocative for them to appear barechested.

In both cases, men can go veil-less and shirtless.

Why is one a social level value, and the other an intellectual level value? 
Why is defeating the first a victory for the "intellectual level", but 
defeating the second not?
