This topic is not up for grabs or opinion. From the Dogmatic Constitution* Lumen Gentium:*
“But the plan of salvation also includes those who acknowledge the Creator, in the first place among whom are the Muslims: these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind’s judge on the last day.”
and
Nostra Aetate:
“The Church has also a high regard for the Muslims. They worship God, who is one, living and subsistent, merciful and almighty, the Creator of heaven and earth (Cf. St. Gregory VII, Letter III, 21 to Anazir [Al-Nasir], King of Mauretania PL, 148.451A.), who has spoken to men. They strive to submit themselves without reserve to the hidden decrees of God, just as Abraham submitted himself to God’s plan, to whose faith Muslims eagerly link their own.
From Pope Paul VI:
“Then [we refer] to the adorers of God according to the conception of monotheism, the Muslim religion especially, deserving of our admiration for all that is true and good in their worship of God.”
From the great John Paull II:
“Dear Muslims, my brothers: I would like to add that we Christians, just like you, seek the basis and model of mercy in God himself, the God to whom your Book gives the very beautiful name of al-Rahman, while the Bible calls him al-Rahum, the Merciful One.”

The doctrine of the Catholic Church on this question is not ambiguous. Of course Cardinal Dolan, as a Catholic bishop is going to uphold Catholic doctrine. When he is criticized for this statement, he is being criticized for his catholicism, an odd response indeed from Catholics.
I think it also important to remember that Catholic Answers is a Catholic apostolate.
