I am the vine; you the branches: he that abideth in me, and I in him, the same beareth much fruit: for without me you can do nothing (John 15:5)

Protestants reject God's predisposing graces and so they can never progress, for all our steps toward God are given to us by God, we practically do nothing. It has nothing to do with intelligence and EVERYTHING to do with God.

Catholic Doctrine on Grace
 
Outside of the Catholic Church there is no sanctifying grace:
 
Although, predisposing or prevenient graces are given to anyone of those outside the Catholic Church, so that they can turn to God, change their lives and enter the Catholic Church, for without these graces no one would ever convert.  However, outside the Catholic Church no sinner can attain sanctifying grace, the state justice wherein one can receive in their soul the  indwelling of the Holy Ghost. They can't receive sanctifying grace because they are in a perpetual state of mortal sin, since there is no way for them to receive remission of sin outside of the Church.
 
DOGMA:

Pope Boniface VIII, Unam Sanctam, Nov. 18, 1302, ex cathedra: “With Faith urging us we are forced to believe and to hold the one, holy, Catholic Church and that, apostolic, and we firmly believe and simply confess this Church outside of which there is no salvation NOR REMISSION OF SIN…”

Some people who are not visibly Catholic, can have remission of sin, but it is INSIDE the Church, even though only God sees that it is inside, and man cannot see it. It's essentially conversion.

Protestants are MENSA material compared with Catholic modernists.

Faith is not the outcome of an exercise in logic, nor is it anything to do with intelligence, neither does lack of it have anything to do with ...  uh...density.
.
My brother had an injury at birth which meant for him a loss of some physical and mental capacity. He received the Faith through the sacraments just as any of us do, and it was nourished by good teaching and example on the part of my parents. He never once deviated from the truth of the One Holy Catholic and Apostolic Faith; in fact loved God with a passion. He is now in Heaven glorifying God!
.
In short, Faith is a gift of God, which needs the right nourishment. Protestants have neither of those two crucial factors.
.
The question is what are we doing to show protestants that there is a Way to God's infinite Love and Mercy and Eternal Salvation. I've learned that it is rare that protestants come to Faith through reasoning. Some wise person once said: You cannot reason people out of something they were not reasoned into.
.  
Best thing is prayer and example.

how can you say protesters do not have faith? That is all they have, it seems.. meaning all they have is a belief (faith) in Jesus, they do actually have Jesus (the Real Presence, the Eucharist)
I disagree. They do have faith... they have faith that tells them Jesus is the truth.. and that faith, if followed to its logical conclusion (there's that L word again) will lead them to the Catholic Church, if they do not resist.

i am far closer to your view than Tradhican's. In fact, I agree w/ it 100%, assuming that is exactly what the Church teaches, but it may not be EXACTLY. From my understanding the Church teaches that if a person is "catholic in the inner forum" of his being, he has a chance of being saved. And of course if he dies b4 he can officially enter the Church, I know God is merciful. He looks at the heart, as it says in some book of the Old Testament (when David was chosen by God)... "Man looks at appearances but God looks at the heart"
