A question for Cardinal Sean O'Malley

Your Eminence, as one who was excluded from Catholic schools (even though my parents were cradle Catholics entirely loyal to the Magisterium of the Church who always lived a sacramental life), I find it strange that you now claim that no categories of children have ever been excluded from Catholic schools.  One of your very own Blog readers has admitted otherwise in my previous Blog post dealing with this subject.

But my question doesn't pertain to my being excluded from Catholic schools.  Rather, it has to do with the words Our Lord Jesus spoke in the sixth chapter of Matthew, verse 24: "No one can serve two masters; for he will hate the one and love the other, or he will be devoted to the one and despise the other.  You cannot serve God and mammon."  Now, mammon can represent either money or any other created thing which stands in the way of a total commitment to the Lord Jesus.

My question: By allowing children of homosexual households into Catholic schools, are you not thereby inviting violence and disorder?  After all, how can these children be expected to serve two masters?  Will they not come to hate the one and love the other?  Will they not be devoted to one while despising the other?  Either these children will come to fully embrace Catholic teaching and thereby be set in opposition to their parents illicit sexual behavior, or [and this is the far more likely scenario given that children tend to love their parents or guardians], they will come to despise the Church while condoning intrinsically disordered behavior which have they grown accustom to being exposed to.

Was Our Lord wrong Your Eminence?  Can a kingdom divided against itself (Mark 3:24) really stand?  Can children of homosexual households really be expected to serve two masters?  I apologize if my questions are difficult.  A hazard from studying philosophy.
