Welcome to CathInfo.
Thankyou!
I'll debate some but most of the issues: sedevacantism, Baptism of blood/desire, the VII Church and validity etc... have been beaten to death and Catholics of goodwill I believe can disagree.
If God wills it there will come a True Roman Pontiff that all Catholics, and the world for that matter will recognize, he will be a Saint sent from God, and he will settle all issues. Probably with a True Second Vatican Council after the present one is abrogated and condemned.
