Questionable. What if they're mostly anti-white racists who feel a nationalistic imperative to kill us? Just asking.
Laughable claim. Considering that 1. Mexicans are racially mixed, with "white" among their gene pool 2. Generally hate blacks more than whites when the come here and 3. 1/3 of all Mexican American females, of ANY generation, intermarry with us gringos. Doesn't sound like the "anti-white nationalist" fantasy of yours.
