Why should a woman who is beaten by her husband not be allowed to divorce him and remarry?  That is the whole deal.  The rich and famous who remarry are welcomed with an annulment regardless of their situation and the deserving are snidely confronted with "pastoral mercy" and told that they can spend their lives living as "brother and sister" or being in "Communion with the poors" because of one mistake with their lives.  That is the issue.  The rich get a second chance regardless of whether it is deserved while the normals get told tough lucky and we don't care.
