The Asians have immense intellectual capacity, as well as a decent comprehension of the natural law in many cases, and that is why they are so hard to convert. It is like trying to convert those in Vatican II. Because they already feel they are moral and good, they don't think they need to change.
They lack the spirit of submission. They look obedient and meek, but there is a secret pride.
Mexicans are not intellectual giants quite as often, to put it diplomatically, but they are hard workers and humble, that is why so many of them gravitate towards Catholicism. They are like natural-born St. Josephs.
Vatican II has brought out the worst in all nations. The Mexicans that used to be humble have had their "inner Aztec" unleashed, they now prefer these Novus Ordo masses that smack of voodoo and barrio block parties. Where are the little old ladies with their Rosaries now?
But it shows you how deeply-rooted Catholicism is with Mexicans, that they have made an unofficial "saint" out of a drug-runner. I can't remember his name, but there is a Robin Hood figure in current Mexican folklore who is the patron saint of thieves and drug-runners, sort of a Che Guevera type, they get him tattooed on themselves as if he were Jesus. It shows a religious impulse, but badly misdirected. Yet what other nation even shows such an impulse?
The Mexicans are simple, warm people, but they need to be led and guided by Europeans, not necessarily in terms of being colonized, just in terms of learning from them. Without that guidance, they descend into superstition, which then passes itself off as the true religion.
