I wish you were in the Catholic Church. I would ask you to teach me to play Go.
I refuse to argue about the sede issue, but... You must lead a very solitary life with that attitude. So do you just sit in your house and refuse contact with anyone who doesn't share your views, or what?
Every day we have to interact, get services from, learn from and even obey (such as in the workplace, or the police) atheists, pagans, other kinds of so-called "Christians", you name it... but if a Catholic believes in the pope, they're a leper you want nothing to do with?
Wow... And here I thought we were supposed to love... LOVE... even our enemies, and those who hated us...
