I'll tell you what: I don't think a custodial father should lose physical custody solely due to his choice to go to college! (key work here is SOLELY) Anyway, what did you want me to say? It is not disturbing that a father obtained custody of a child, it is the reason that the article states for the custody change. I would think it was just as unfair if it happened to a father. And, trust me, it works both ways. If anything, this argument would be used even more potently against custodial fathers, as you imply the automatic assumptions many people make. So it is good that NOW (or whoever) takes a stand against this for custodial PARENTS, since the decision can be pointed to as precident for both genders. Their motives aside. I believe it would be overturned on appeal with either gender if this is the sole reason for the custody change.
I am not making assumptions, just posing possibilities due to the vagueness of the article.
