No, no. Not that one.
Sometimes other folks can say what I’m thinking more eloquently than I can. This is one of those times. I invite you to click on this link to read a NYT piece in which two grammarians debate which rules to adhere to, and which to let slide.
If I have to choose a label, I find that I can’t. I have elements of both prescriptivism and descriptivism in my grammatical worldview. Apparently that’s not entirely bad.
I can live with that.
