Real.
What’s interesting in that the first paragraph of this has a big distortion, or lie or whatever one wants to call it:
“Of course this is not a problem for a large number of Protestants who no longer believe in the real presence of Christ in Holy Communion anyway.”
I guess the author feels he can get away with such an insult on a technicality. That real presence means something technical in Catholic Doctrine.
In Internet parlance, the author is trolling.
But it is not capitalized and is presented as an attack and insult on Protestant’s beliefs.
