No body gives their lives for liberalism any longer. It is not getting new recruits. Why commit your life just to be a glorified social worker/psychotherapist? Vocations are coming from big families, homeschooling families, orthodox families. Many protestant ministers, fed up with the heterodoxy on matters of faith and morals, are converting. Some of them bring a majority of their denomination with them when they convert. Some do it privately and quietly. But the number of protestant ministers alone over the last 15 years is into the thousands. Its like the reformation in reverse.
Liberals generally don't have children or at least as many children as orthodox Catholics(see allend's comments on contraception, see my profile page regarding same.)
Those embracing Catholicism (and there are many, unlike mainstream protestantism, which is dying) are coming in because of orthodoxy. The converts in the news clipping I posted are not Catholic immigrants. They are newcomers to Catholicism, and our ranks are swelling, while liberalism's ranks and mainstream protestantism's ranks are dwindling. The same is true for "orthodox" conservative evangelical and fundamentalist churches. The Churches faithful to Christ and resisting liberalism continue to swell while liberal churches dry up and fade away.
You might ponder from a PR standpoint (I won't argue theology with you, I simply am not qualified to do that), whether Catholicism is in the fundamentalist box or the mainline box. I am quite confident it is in the latter in the US. And you do know about the deep inroads that fundamentalist Protestantism is making in Latin America don't you? The numbers might quite amaze you.
You know now that you mention it I see a lot of that going on... Gives hope.
