You appear to be a very patient person, let me pose a brief metaphor.
You and I, I am sure, love America. In the last six years this wonderful country has been ravaged. Are you less of an American. You would not call yourself something else.
Yes?
Poor analogy. While the Constitution is still in effect it is still controlling. The ravagers haven’t yet to call those not following or agreeing to their agenda sinners/criminals. When the hierarchy of the Catholic church changes what it means to be Catholic are you still Catholic? Despite what others have claimed here, Catholic teaching requires you to submit to the teaching to remain Catholic. So on this issue you say ‘they’re off base, this isn’t a faith thing’. Although the encyclical called denying AGW is immoral. At any rate if you don’t submit your intellect, how are you still Catholic?
