re: Pew poll shows support for same sex marriage dropped

People that don't want to get married are "business couples". This means it makes sense to them to get married be it financially or for whatever reason. A couple that doesn't want children have to be a little on the self absorbed side. Couples that can't have children got married with the hopes of one day having children and are just not able to.

ETA: By the way, financially could fall under sharing insurance policies for just one example.
