Don't exempt Incred: It should not be difficult for him to name a few priests he considers orthodox in doctrine, if he believes there are any left.
Yes, you are probably right. How difficult can it be for a trad Catholic to name priests who are orthodox in doctrine. It wouldn't bother me if it were sedevacantist priests who were named. If they believe that no orthodox priest is left in the world, then let them say that, so that we at least know where they are coming from, and it would be helpful to know why they believe that way.
