The bishops can oppose injustices in society like abortion.  But they say nothing about women being exposed to rape and sexual violence at home, in schools and in places of work.  Women have the right to accuse the bishops of being complicit in the sexual abuse of women.  Nor do the bishops urge male parents of babies/children to pay support for the care of their children.  

If the bishops are going to oppose abortion, they should be just as adamant about men paying a fair share to support the children that women often have to raise on their own.
