Sir, dissident Catholics might have "moved on."  "The Church" has not.  What dissident Catholics believe is quite irrelevant.  Do not confuse and conflate "Dissident Catholics" with "The Church."

No one cares what what these guys think about human sexuality? Who cares what dissident Catholics think either?
The Church is not a democracy.  I am sure the Arians in the fourth century thought the same thing: no one cares what these guys think about the identity of Christ.  Heretics in every age have been saying that.   "Who cares what the bishops think? We are going to do it our way!" Go do it your way. Go found another Protestant Church and show the bishops how you think it should be done. 

No one threatens someone with eternal damnation for opposing the social teaching of the Church?  That is news to me.  Jesus seemed pretty clear that those who do not love and care for the poor are eternally doomed.  Ever hear of the rich man and Lazarus?
