After reading my previous post carefully, I could say that this question is different from this question: Is "It's people" grammatically correct?.
Suppose, there is this monolog:
There are times when I loathe people. Mind you, I'm people.
I mean to write a trait of hatred aimed at a group of "people" and I belong to that "group" as well. I hope that makes sense.
Is it at least natural or perhaps can be grammatical if we treat "people" as a noun. Do I have to add an indefinite article then? I did try to search "I'm people" on Google and I found there's a song called "I'm a people". However, I don't know whether it has a same meaning as mine or not. Also I need to know whether the sentence —our topic above— is correct. If it is, correct in a sense of natural sounding or grammatical or else?
