My guy you literally said “Hell no [it isn’t grammatically correct]”. I simply said “yes it is” and elaborated, because apparently you didn’t get that part. There is absolutely no “you just said what I said but different” here because I did not, I contradicted you even. You can’t say “yeah usage defines what’s correct and all but also this common usage is incorrect”, that’s just stupid. Even if you mean “non-standard” when you say “correct” it’s still completely wrong, because it is standard. But be a baby I guess.
