What really gets me, when smart articles like this come out, is the intellectual dishonesty of liberals that wraps the label "religious inspired intolerance" around any argument against the "liberal" things they try to defend. Even an atheist can read the study and conclude that "cohabitation" does not trump marriage, at any time in the "relationship".
So what? Every year the same story gets written. It's not going to change anything and alot of successful marriages started as living together. Mine included.
