This is the kind of mushy thinking and terminology that gives practicing Catholics a bad name. We need better terms - how about "faithful Catholic"?
Better yet, those who have left the fold in truth just need to stop arrogating such terms to themselves. It may make for good copy, but it does nothing for the rest of us.
It's not like we need a litmus test or anything, but how about we start with the Creed and work our way up from there? There's no use dumping on the hierarchy, because we're all in this together (it's one body). The Kingdom of God is messy, boys and girls; God shines his sun on the good and the bad alike.
