But the west is insignificant when it comes to the growth of Catholicism. 
The edit you added to your comment shows that in the past 60 years, the catholic charismatic revival has 120 million followers. Many of those people were likely already Catholic who switched over. But there are more than a billion Catholics so that seems a little insignificant.
It doesn't make sense to look at numbers like this and say 'this movement is growing Catholicism' when this movement is US-centric and most of Catholicism's growth happens in Africa and South America.
The adoption of first-world pleasing policies doesn't matter for the Catholic Church' growth based on the facts. It's being done to protect the church from losing more people, and doesn't significantly contribute to recruitment.
Online, subs like r/Catholicism and r/CatholicMemes are dominated by this movement. While sometimes it is true that future Catholics want a traditional church environment, I think these communities drastically overestimate that.

Are these subs supposed to be representative of Catholics at large? 
I would guess people who care enough about catholicism enough to post in a reddit sub about it, but unorthodox (punny!) enough to not be able to do that through actually participating in their church are going to be fairly unusual people compared to the average Catholic. >

I am referring to the online community here. Sorry. Particularly the “I’m better because I go to Latin Mass” people.
Most Catholics on Reddit are lovely people—this is a broad internet movement and one that isn’t huge, thankfully. >

But what is "the online community". Do you mean catholic people on reddit, or people who voluntarily choose to go r/Catholicism ? >

Most Catholics on Reddit are great; it’s a ultratraditional minority I have some issues with. These aren’t necessarily confined the certain subs. >


Vatican II was meant to modernize the church, and it was a great success. Acceptance of gay people into the Church (not in marriage, but surprisingly progressive), the creation of a Catholic community (“peace be with you”, another thing disliked by TLM) and yes, Christian music with gasp guitars in it. It has been successful, in my opinion as the Catholic Church is a rapidly growing institution. Overall, their rejection of aggiornamento that has grown the Church is strange to me.

The growth of the catholic church is happening primarily in Africa and South America a where few care about this type of thing except maybe the non-latin mass and even then homilies are still done in the local language. A modernization of the Church to better align with contemporary first world society happened during this time, but do you have any evidence that this modernization caused the growth in popularity?
Also I just wanted to note,

PS: As a side note, a minority of these people use Catholicism as a cover for right-wing beliefs [...] VERY anti-Israel.

Being anti-Israel is not an exclusively right-wing belief. >

What do  you think about the rest of my reply? >

I just think this proves there is certainly a Catholic audience for a modern movement, and many in the West interested in Catholicism not out of its traditions.
