Thinks non-believers are not fully human.

I wouldn't be too hard on him, though, as he apparently can't tell the difference between the capacity to "search for transcendence" (as he puts it) and the varying degrees to which people apply differing evidentiary standards during the said search (such as it may be).

It's that capacity that makes us human, whether we decide to let it be fulfilled or not, through whatever reasoning. And, obviously, non-believers don't deny that capacity. Even this Cardinal has it.
