Let me clarify!
In my case it is more than an opinion, other sedevacantist may have a doubt, but I don't.
You have no doubts? Great!
But does that make your position binding on everyone else? Does it mean it is objectively true?
If I believed that the moon was made out of blue cheese, and I had no doubts-would that make it true? Would everyone else have to believe as I do?
In matters that are
objectively doubtful, such as sedevacantism, Catholics may hold varying
opinions. Just because you
subjectively have no doubts, does not mean that the matter is not
objectively doubtful
