Thank you for your personal opinion. From the Catholic perspective many Protestant doctrines are correct, some incorrect- with our relationship to the Church which Christ initially established more or less perfect accordingly.
It is not my opinion but rather a fact that the catholic church is teaching many false doctrines and pointing out the Protestant church is just as guilty on false doctrines isn't helping your argument.
To name just a few.....
Matt 6:7 But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.
1 Tim 2:1-7 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men; 2For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty. 3For this is good and acceptable in the sight of God our Saviour; 4Who will have all men to be saved, and to come unto the knowledge of the truth. 5For there is one God, and one mediator between God and men, the man Christ Jesus;

Forbiddung to eat meat and priest to marry
1 Tim 4:3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.

The Church is not related to salvation
1 Tim 2:4 Who will have all men to be saved, and to come unto the knowledge of the truth.
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

Eucharist NOT the body of Christ
Christ said the bread was His body does that make bread His flesh.
Luke 22:19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
Jesus said he was a vine does that make Him a plant.
John 15:5
I am that vine: ye are the branches: he that abideth in me, and I in him, the same bringeth forth much fruit: for without me can ye do nothing.
So if Christ said bread is His body then by that logic Christ is also a vine too?
Christ also said he was a Rock so is he a rock too?
1 Corinthians 10:4
And did all drink the same spiritual drink for they drank of the spiritual Rock that followed them: and the Rock was Christ.
So then is Christ a plant
John 15 : 1 I am that true vine, and my Father is that husbandman.
John 15:5 I am that vine: ye are the branches: he that abideth in me, and I in him, the same bringeth forth much fruit: for without me can ye do nothing.
Is Christ a Door?
John 10:7
Then said Jesus unto them again, Verily, verily I say unto you, I am that door of the sheep.
John 10:9 I am that door: by me if any man enter in, he shall be saved, and shall go in, and go out, and find pasture.
Is Christ an animal
John 1 : 29 ¶ The next day John seeth Jesus coming unto him, and saith, Behold that Lamb of God, which taketh away the sin of the world.
Is Christ food?
John 6: 35, 48 I am the bread of life.
Is Christ a light? The fact is yes because light existed before the sun moon an stars were created?
Gen 1 : 3 Then God said, Let there be light: And there was light.
4 And God saw the light that it was good, and God separated the light from the darkness.
5 And God called the Light, Day, and the darkness he called Night. So the evening and the morning were the first day.
6 ¶ Again God said, Let there be a firmament in the midst of the waters, and let it separate the waters from the waters.
Rev 22 : 5 And there shall be no night there, and they need no candle, neither light of the Sun: for the Lord God giveth them light, and they shall reign for evermore.
John 8 : 12, 9 : 5 I am the light of the world.
