An Observation

From presentations in my composition course this morning, where students were presenting their plans for a utopian society:

in my 8:00 class, both groups presented utopias in which marriage was rigidly defined and strictly upheld (in one case, you were able to marry only once, without exception even for death of a spouse), and in which adulterers were put to death.

in my 9:30 class, both groups presented utopias using exclusively "open" marriages, where one could conceivably have any number of sexual partners.

I'm sure this means something, but I'm not sure what.
