Seriously, what is their lame excuse? Why haven't +Dolan, +Sanborn, +Pivarunas, and all the other Sede bishops elected a pope yet? They must have some lame excuse.
I don't think that anyone has directly answered the above question, as of yet.
Evidently, the above sedevacantists don't believe that there needs to be a Pope of the Catholic Church. Or, if there is a Modernist Pope, than he's not really a proper Pope, so it's better to not have a Pope at all. Therefore, there is no Pope.
I agree too that the sedes should elect their Pope, and stop bothering everyone else in trying to force sedeism on all of the trad Catholics (or the Resistance Catholics, rather. I think they've given up on everyone else).
Maybe if they have their own Pope, they'll leave the Resistance trads alone. Or, maybe not. On second thought, if the sedes elected a Pope, they might insist that all trads accept their Pope, or this means that they are not really Catholic, and may be condemned. I can see that as a potential problem with the sedes electing their own Pope. They will become even more annoying, if they have their own Pope.
But then again, they might not be able to come to a consensus. After all, sedeism is highly individualistic. How could they ever agree on who it is that would be Pope? A sede conclave could potentially go on forever, with endless debates and opinions about who should be elected Pope.
