I’m American and don’t get it either. When I was younger that was the only cheese I knew and I decided I didn’t like cheese because of it. It took a long time to realize that stuff isn’t real cheese and that the real stuff is very good.
I also think it isn’t legal to call some of it “cheese”. I know Kraft singles at the very least uses some deceptive phrasing to say it’s cheese-like or cheese-flavored or something like that instead of calling it “cheese”.
