This is troubling!
But if you know some Spanish and go to the YouTube video page this video is taken from you will read there is a discussion of whether or not Arabic is required to become a Muslim.
While it is not required, it is so heavily emphasized that Islam, thankfully, has the drawback of being difficult to convert to.
With a major Evangelical Revival occuring in South America, the reverse is true. Evangelical missionaries try to learn the language of the natives. The natives are not required to learn the Hebrew or Greek of the Old and New Testaments, respectively.
The upshot is that converting to Evangelical Christianity is very easy.
