Many years later, she's out there. She's still doing the nitty gritty. Could of cashed in and been a public speaker. I appreciate and respect what she does.
There is no such thing as basic grammar, FFS. If you knew what they meant then they conveyed their meaning perfectly and you are being needlessly rude. Unless you are grading a paper that has specific requirements for Standard American English(TM) there is absolutely no reason to be a cock about someone else's perfectly expressive language.
“we regularly demand of people that they suppress or deny the most effective way they have of situating themselves socially in the world”—their language (Lippi-Green 2011, p. 63). Institutional function often depends on a particular set of beliefs about how language, especially the standard language, works. Lippi-Green and others refer to this set of beliefs as the standard language ideology, defined as “a bias toward an abstracted, idealized, homogeneous spoken language which is imposed and maintained by dominant bloc institutions and which names as its model the written language, but which is drawn primarily from the spoken language of the upper middle class” (Lippi-Green 2011, p. 64; see also Agha 2007).

Yeah those are not citations to the point, they are anecdotal at best.
I'm not a native speaker, my first language is french, and I used to make that mistake, which is why I brought it up. Get over yourself, there's no way to say "that's not a mistake they would make".
"This error is more disruptive for natives than non natives" doesn't mean what you think it means. Sure maybe it's not as frequent, it's not a basis to assume anything, or to say "I'm a native speaker".
