That is the beginning and it always is the beginning.  It does harm in a relationship with faith to summarily dismiss someone who one presumes is sinful.  

I think Paprocki should take a firm stand and get every couple who uses contraceptives to own up and then forbid them access to any Catholic activities - Eucharist, singing in the choir, teaching at a Catholic school, funerals, being a god parent.  All of it.  Same for a Catholic who is remarried without an annulment.  He should tell other Catholics that it is okay for them to spy on their neighbor and report to a priest or to him any Catholics they know who are so terribly sinful.  Oh, same for knowing any Catholic who is "living in sin" while unmarried.  And then, if he can't prove any of these people caught in sin did not go to confession before dieing, then deny them funerals.  Just go all out- don't just pick on LGBT "sins" as if no other sin counted.  How will Jesus judge Paprocki's judgmentalism?
