The rosary is attacked only because it it Catholic. Similar (in purpose) artifacts are extensively within the Jewish faith without criticism. Isn't a menorah a mnemonic device to organize prayer over eight days? What difference is there in theory between a rosary and a tallit or a tefillin? Why isn't a mezuzah subject of criticism. In fact isn't written scripture, prayer books and hymnals exactly the same thing as a rosary?
The answer lies in the fact that there are greater social and FR rules against the unfounded criticism or bashing of Judaism than there is against the unfounded criticism and bashing of Catholicism.
As I noted before, Anglicans and Lutherans also use Rosaries, though it is not as common as among Catholics. I cannot escape the feeling that there is NOBODY that the anti-Catholics hate more than the Mother of God.
"How beautifully difficult, and therefore true." Advice one might keep in mind when reading Matthew, particularly. It's difficult sometimes; it's work. You need to contribute something of yourself to it. Just repeating verses from Matthew will not make you a holier person either.
You are aware, I'm guessing, that criticism of anything Catholic can be summarily dismissed if you say someone is just criticizing because it's Catholic. That defense is similar to crying "Ad hominem!" when there is none, when one has made a point that needs accepting or refuting.
