Because that's not what Gamecock said. He said, "So the late Pope and the Catholicism are both wrong!?!
If you want me to be blunt, then yes, Pope John Paul II was wrong to say that. I may get the Riot Act read to me now, but I really don't care, since hasn't making an ex cathedra teaching. As for Catholicism being wrong, I certainly don't believe that. As for Nostra Aetate and the statement from the Catechism, I do think they are problematic, since Mohammedanism is a false religion.
But that is clearly what he meant. He obviously wasn't trying to get you to denounce the entirety of Catholicism. He wanted to know whether you thought that Catholicism is wrong on this one point, i.e. whether Muslims worship the same God that Catholics worship.

Ok, here's your "Riot Act":
"Such is the nature of Catholicism that it does not admit of more or less, but must be held as a whole or as a whole rejected" - Benedict XV
