We have a word for those people in Spanish:
Malinchistas.
In Mexico there are
less than 5,000 Muslims total (less than 0.01% of the population), despite having
an Arab-descended population of over a million. I know Mexico is definitely not all of Latin America, but it does shed light onto how most people view Islam. If I recall correctly, the largest single population of Muslims in Latin America is in Argentina, where they (not surprisingly) have a much larger Arab-descended population (over 3 million), though the majority of those people are Christian, just like in all of Latin America. Nevertheless, Islam represents roughly 5% of Argentina's population. (But it's very new; the
first mosques there were not even built until 1983.)
This is not some wave, and if it were it would be because of community-internal factors (I suspect more related to life in the USA than anything, as that's where the story is coming from), rather than something to do with Latinos suddenly being attracted to Islam as a religion. You don't name your cities
Matamoros for nothing! (Actually it's from
an appearance of the St. James the Apostle in Spain, but the point is that they keep it that way.)
If the life of cultural Catholicism and the abandonment of all actual authority and community in the modern Roman Catholic Church to which the majority belong is not fulfilling (and I understand why they'd feel that way; I was Roman Catholic too, so I've been there), they are far more likely to turn to Pentecostalism or something else than to Islam. Notice how the figure in your link was an ex-gang guy? Yeah. That's because Islam does its best recruitment from among criminals.
A growing number of Latinos are also turning to Orthodox Christianity. Undoubtedly more than are turning to Islam (particularly if we look globally, as Orthodoxy is arguably stronger in Guatemala and Bolivia among indigenous people than among Latinos in the USA).
