I agree with the analogy, but you should realise that the downvotes and pushback are not for any lack of logic but because saying that they lack logic is a downright insult.

All people have logic, even if flawed. Logic is the expression of the Logos, which is the Word of God that exists within each and every one of us. Sometimes that logic is distorted through false knowledge and bad lenses, or sometimes it's just different because they just have different spectacles. But everyone including u/Russian_Hacker's Uncle has the Logos and thus logic, and to deny that is to say that they don't have free-will, consciousness or any semblance of personhood. In a way, the way you refer to non-Catholics is as if they were somehow lesser and alien, even if that is not what you intended.

Before you take the twig out of another person's eye, ought you not take the log out of your own? Otherwise you will provoke the ire of other Christians, as you face here, and being a fellow Christian is not going to assuage their ire.

But that is beside the point. Let's walk back a bit. Who says that his uncle has left the Church? The Church is not the monopoly of the Roman Vatican, or of Orthodox Constantinople, or of Russian Moscow, or of the Anglican Queen, or of the Lutherans, the Protestants and the Evangelicals. We may not be together in communion now, but maybe one day we may once again reunite in a seamless whole under One Christ.

But for now, his uncle has seen something distorted in the RCC and decided that he did not have it within him to endure those distortions that befall Rome. That is understandable and not everyone can afford to do so and survive spiritually. Then he found greener pastures elsewhere in the Baptists. This is much like your other analogy: "maybe you better leave the U.S. you have some nasty pedophiles running the place." If a person cannot survive in the cities, in the blue states, in the U.S., then perhaps they really do need to live elsewhere. Perhaps that is where they will flourish. If a person cannot fight the corruption of the False Pope and the Deep Church (and yes, they currently reign in the Vatican!), perhaps they should leave that particular battlefield and instead cultivate their faith in a different more peaceful field.

Perhaps that is what God intended for them, and that is a perfectly logical decision. Sometimes you just need to decide that a different place is the place that you will flourish. But if you choose to remain in the U.S, to remain in the RCC, then do so knowing that you may be called by God and his servants in the fight to retake them both.
