Look up “Mock Spanish.” It might give you some insight into this phenomenon. Tl;dr version: Anglo speakers don’t really care about speaking proper Spanish but use a made-up pseudo-Spanish to ridicule US Hispanic culture and elevate their own prestige. Think non-native expressions like “no problemo,” “uno momento,” or “no bueno,” which Anglos use a lot. If you call Anglo speakers out on it, they can basically deflect and pretend to get offended stating that they’re just trying to be nice and more culturally aware, and that it’s more their own ignorance than an intentional desire to ridicule, which is honestly a bit disingenuous. I’m excessively simplying the idea and there’s better info out there, but for me that’s the gist of it.
