Yes it is. Language is defined by usage, people not liking how a word's usage has changed doesn't make it "incorrect" by any stretch of the imagination. Culturally it's seen as informal, maybe, but there's no "incorrect", it's completely standard now. You wouldn't avoid teaching ESL students that usage, for example.
So what you're saying is you didn't read my post. You repeated literally the main content of my very first sentence like it was the first time written in this thread.
Fair enough, now you're blocked and I'll never have to read your drivel again.
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.
I remember when this really started taking off about 20 years ago. A warehouse guy where I worked walked into a conference room full of people and declared that “The warehouse is literally full of SHIT!”
I was like, “Eeew. That's disgusting.”
A few people laughed.
he said, “No, literally!”
several more people laughed.
Someone explained literally vs figuratively.
It really seemed to take off with the popularity of the Kardashians. I literally blame Kim for this issue.
