You do not understand the reasons for engaging in Catholic apologetics. The primary goal is to keep Catholics Catholic. And to get them to embrace the whole faith, not just the comfortable parts.
Next is to get Catholics back.
My own third goal is to convert Christians, both non-RCs and RCs themselves, back to the scriptural foundations regarding family planning, and thus turn back the tide of abortion and homosexual juggernaut, and get them to stop using abortifacient contraceptives. With committed Christians this is not difficult, as committed Christians are pro-life. And since barrier methods are Onanistic but also ineffective, the logical next step is NFP for those who have grave reason for not being providentialist.
The next goal is to bring home the non-RC Christians, and finally, the unbelievers.
What precisely do you hope to accomplish with non-RCs
With the ones I am directly debating here? Not much. But they serve a purpose.
Keeping Catholics Catholic is simple. All an average Catholic needs to know is that there are valid answers to the anti-Catholic charges, whether they are scriptural or historical or logical. Catholics just need to know these anti-Catholic charges can be answered. Otherwise in a vacuum, they start to doubt.
For the fence sitting non-RC Christian, these apologetics get them to search deeper and pray. No one will decide based just on this thread.
And the average Catholic or non-RC fence sitter doesn't give a hoot about OP's excellent exegesis of Calvin and predestination. Its too arcane to be the primary reason for conversion. Most reading this thread gloss over posts more than several lines long. OP's posts are highly educated, but their speculative nature precludes them from changing hearts.
Non-RC committed pro-life Christians suffering the teeth grinding frustration of the pro-life battle and the lack of any real victories read a thread like this and realize that abortion is intimately associated with the contraceptive mentality.
It quickly dawns on them that this absolutely essential piece of the puzzle has been withheld from them in protestantism in general and their own church in particular.
The majority of the hundreds of pro-life protestant pastors who have converted to RCC in the last 10 years started down the path of conversion after examining the roots of the legalization of abortion, and why protestantism abandoned its teaching against contraception.
Not all non-RC committed pro-life Christians desire conversion, and that is fine.
But if they too take up this call to reexamine this central teaching of Christian moral theology and its relation to abortion, they have the opportunity to take it back into their own churches and change others hearts, and begin to see a re-evangelization of the Christian churches on this issue.
From that re-evangelization of the Christian churches on this issue, someday will grow the first true victories in the pro-life battles.
Until that re-evangelization of the Christian churches on this issue we will not see any real progress on the pro-life battlefront.

That is our primary difference. The "goal " of most Biblical Protestants is to present the gospel of Jesus Christ. It is to pray that people hear and respond and come to repentance, and a saving knowlege of Jesus Christ
Your concern is not their soul it is all about the doctrines of men.
Matthew 15:9 But in vain they do worship me, teaching for doctrines the commandments of men.
What you have not yet figured out my friend is that if one carries Christ in their heart it will be a joy not a burden to be obedient to God. No need for a lecture on abortion to one that is saved by the Blood of Christ. He carries all those laws in his heart.
As Jesus warned in Luke
11:39 And the Lord said unto him, Now do ye Pharisees make clean the outside of the cup and the platter; but your inward part is full of ravening and wickedness.
Your concern my friend is with the law and the outside of the cup..
