Ok, just a word of caution to everyone here.
You can't lump all Protestant teaching into one boat. There are several schools of Protestantism, and while all are heretical, some are farther off the beaten path than others.
For example, I was raised in the Lutheran Church, Missouri Synod. The LCMS is about as Catholic as you can get without being Catholic. They have a strong devotion to Mary, though they are ambivalent about her and are always wary of "worshiping her." Though they see her as not just another girl. They acknowledge that God chose her and made her special. Heck, they're even almost right on the Eucharist! (Transubstantiation vs. ) Cosubstantiation
So please, don't make the mistake a lot Protestants do about Catholic teaching and lump all of the bad together with the good. We are all allies in the same fight, and that means we have to at least make an effort to understand what their teachings really say and the differences between sects. Otherwise, we're just spouting off about things from hearsay, and that's a lousy position to be in.
Don't let the fact that you know Catholicism is the True Path lead you to contempt of those who worship the same God but are misgided in their route to him. They've got a lot wrong, but they're trying their best, and many would probably make the leap to the Catholic faith as I did if presented doctrine rather than snarky one-liners.
Remember, we are Faith and Reason. Use both.
