Hear me out. There’s nothing innate to an object that makes it “food”. It’s an attribute we give to certain things that meet certain qualities, i.e. being digestible, nutritious, perhaps tasty or satisfying in some way, etc. We could really ingest just about anything, but we call the stuff that’s edible “food”. Does that make it a social construct?
Well if you really thought this person was stupid, what was the point of calling them such? You just want them to feel terrible about themselves? That’s pretty dumb. If it’s such a stupid question, you could share an intelligent answer to help. But it seems like you’re just triggered and that it probably happens a lot to you.
