I suggest that you go back and reflect on the fact that this was an act of Church authority and not your private judgment.
Can I take this your comment as a confirmation that you finally have understood what "manifest heretic" means? Did you understand that the Church judges manifest heretics as heretics, pure and simple, even if they objectively, in the eyes of God, may not be heretics, but just erring?
Let me assure you, that I am well aware that I own no apostolic mandate, and that I am able to distinguish between the judgment of (true or false) Church authorities and my own judgment.
Are you aware, that all Catholics use their own judgment to decide whether they accept V2 or not, whether Bergoglio is a Pope or not, whether they resist an apparent authority or not, etc. pp.? You don't seem to, coming up with the tedious "private judgment" drivel.
