I think you're purposefully missing the point. The Catholics ones are indeed Catholic, but the number of Mexicans, that identify as actual Catholics is less than half of the population.

"but if they become Evangelicals, they become more conservative and pro-life."

Less than half of them.

No. the majority of Hispanics are Catholics.

The vast majority of Hispanic immigrants arrive as Catholic.

If they become Evangelical they also become more pro-life and politically conservative voters.

Why does that bother you?

People who are pro-life and pro-marriage, and conservative, should be dancing in the streets at this news, it shows a path to reversing the pro-abortion, leftist gains of the democrat party through Catholic immigration.
