You put that very well.
The Catholic Church stands fast against Infant stem cell research, assisted suicide, abortion, artificial contraception, Euthanasia, Same sex unions, etc...
While individual assemblies or individuals may oppose them you can be certain that every single protestant church that doesn't already allow them will within 50 years.
I am always amazed when a Protestant objects to Catholic claims of being the one true church. Does not every Protestant preacher present the teaching of his denomination as being the truth and that of other denominations as being false? Do not Protestant posters here at FR present their opinions as the truth against all other interpretations of the gospel? If they do not claim to hold the one true gospel then perhaps they should add the phrase "but this might not actually be true" to everything they preach.
You may know your Protestant religion well. but you are a very confused individual when it comes to the Catholic Church. Yes, the Catholic Church teaches that the Catholic Church is the “one, true, holy and apostolic Church”, but that is not necessarily what is taught by every individual who walks the halls of the Vatican in Rome. In fact, you actually should be embracing many of them because they’re really trying to sound like you. The Second Vatican Council did as much as it possible could to confuse that issue with adopting their false “ecumenism”, and to lead people to believe that they would be saved by following a religion other than that of the Roman Catholic Church. You may be saved by living a good life “in spite of” your religion, but not “because of” it.
So if that’s your problem with Catholicism, you should be jumping for joy with the Modernist Catholic bishops and popes who promote this false ecumenism and do their best to suggest that those many other false religions are “almost” as good as the Catholic Church. Sadly, some Catholic clerics and religious even go so far as to suggest that one religion is as good as another. Mother Teresa, the soon to be saint of the Catholic Church, has said as much. Sorry, but that is not the true teaching of the Church and traditional Catholics follow the true teaching.
For your information, the Roman Catholic Church is the one and only true Church founded by Jesus Christ, and that every other religion (N.B. every other religion) is false. That includes the Evangelicals, the Baptists, the Muslims and so forth. It is the duty of every faithful Catholic to teach the truth to those who are not Catholic, and to encourage them to join this one true religion. Whether they do or not is their choice. And whether you want to believe that or not (which you clearly do not), is your choice. But it is the teaching of the true Catholic faith.
As for the issue you raise about Rome not being very “likable”, please understand that the goal of the Catholic Church is not to be more “likable”, in spite of the fact that many of the Modernist Catholics today often tend to think that same way. Understand that being a “likable” religion is a Protestant thought, not one of the true Catholic Church. The only issue is the “truth” of what is being professed and what is being followed. You may call that “arrogance”, and at some level it may well be seen as just that; but if you believe that professing the truth taught by the doctrines of the one true Church founded by Jesus Christ is to be “arrogant”, then you are entitled to your opinion. But for a Catholic to deny those doctrines is sinful.
You have to go to Northern Ireland To understand how deep the divisions really are when you cut deep to the root; and what the unrestricted Romanists really feel about you.
Furthermore, some RC posters on FR seem to be political liberals in conservatives' clothing.
They basically are, when their core program is the "social gospel" (to which the Methodists also subscribe), where the emphasis is more on the social part than the gospel part.
