Could somebody please explain to me what the following terms mean...?

Question

"Acting Black"

"Acting White"

"Acting Latino"

"Acting Asian"

Answer 1

They mean that the speaker is prejudiced. When we think of everyone as valuable and normal, we'll live in a better world.

Answer 2

Just people trying to act like a group they don't belong to.

Answer 3

Acting like a "stereotypical" Black, White, Latino or Asian person.  I don't use the term, but I find people who tend to use the term to use it like that.  Pretty silly.
